My senior who is in NIT, suggested me Neso Academy and I told her I already subscribed to the channel. Most of the times, I've written tests right after watching your videos (even finals), thank you for the clear explanation.
Another question is while explaining the discrete part Sir took reference of the graph drawn in the CTS part and have plotted t0,t1....,tn and said that the continuous signal is defined for every value of (t) then again he said we can't find the difference between t1 and t0 as it is not defined at every point of (t) PLEASE CLEAR MY DOUBT ITS A REQUEST TO ANYONE WHO UNDERSTOOD THIS PART.
In the last example I think you may also add the step in which the DTS is plotted, which is the T value. Refreshing things up here, took these classes a long time ago. Clear and great explanation! Thanks
There are two kinds of single depending on the value they take wrt to time So their names are continuous time signal CTS and discrete time variable TTS One which take values for every value of time is CTS other which takes value for discrete values of time TTS CTS representated as x(t) t is independent variable time and x is dependent variable that is signal TTS is represented as x(n) X is signal and n is integer For example the diff in the two consecutive times is T in two consecutive times is 2T in this way we represent it for 1t,2t,3t as for 1,2,3 factor of T is hidden And for representing purpose in TTS, we place arrow below the value TTS takes for integer 0 that is when time was 0 the value it took Thank you #feymanTechnique
Will sir you please prescribed the best book for learning signals and systems for gate along with your videos.Because I likes reading book along with the tutorials
Sir here you have explained that 'dc is not a signal' but at example you told about system where we are using a pump as system and ac as signal. my question is if we use dc pump as system can we consider dc as signal then?
Sir, you talked about DC not being a signal, can you elaborate please? And what about step function, will it also be not categorised as a signal beyond t0?
ex:dts=[1,0,1,2,2,1],from left to right sir you tell that second 1 as a x[n] at n=o.But also can take first and last 1 as a x[n] at n=0.why you only take second 1 as a x[n] at n=0?
Sir can you please explain the effect of P, PI, PID, controllers on rise time, peak time, max. Peak overshoot, settling time in a comparative way? Please sir
Hello Sir, You have explained how n is an integer for uniformly sampled signal then how is n an integer for non uniformly sampled signal. Please clarify it.
Doubt: in last 10:21. If let's say x[0]=1, how can you tell it's 1 of 3rd in series {1,0,1,2,2,2} it can be 1st one know? If it's 1st one the data is wrong again!
sir, can you please upload a tutorial video on Audio-Amplifier using IC tba-810. basically I want to study it's schematic, which I'm unable to do with it's datasheet.
Why do we have to remove T? And how did you just remove T like that? Is it by equating T to 1? Can we cancel an independent variable whenever we want to? I don’t understand
9:55 u said we simply put an arrow at where amp is 1 we take it as n=0 but y u choose middle 1 insted u take first 1 as n=0 ,i am so confused plz answer me
Manoj Karajada we have 2 samples at right of n=0 so we can't put n=0 for 1st sample as we will always right the sample values in order of increasing n.
T is a constant. So T is not gonna change and its not gonna affect the x value. But the integer n affects the T. So we change the representation. I think its a convention to say x[n] bcuz we usually put inside the brackets the variable which affects the value of X , though you can represent the same function as x[nT]. lets say X[y]=10Ty. If Y = n, the X[n] = 10Tn. If X[y]=10y , if y=nT then X[y]=10Tn. So, I think its a convention standard rather than a natural rule to write it like that in mathematics and elsewhere.
In the video of addition of continuous time signal the amplitude is constant b/w two interval if it was a sinusoidal signal or cosinosoidal signal how can we add the signals
Sir could u tell me how to convert continuous time function to discrete time function. Actually i need to know how to convert a differential equation in time domain to difference equation in discrete form
When u told that,'when n=0,x{n} is 1then why didn't you have chosen the first most value of 1when x(-2)...I mean how did u get to know that we have to chose middle 1 rather than choosing first or last 1

Hey can someone explain to me what bro says the term T is cancelled at 7.03
Happy to see that naso academy is growing on UA-cam
Can you explain me how x(nT) and T is cancelled ?
great work sir your teachings are better and understanble than my faculty lectures, lots of love from nit silchar
You explaination is so good , I learn whole course before my semester starts
Can uh plz tell, how many days it takes to complete this entire course
And me also start from today.and tomorrow is my last practical exam of 3rd sem. 💛💫
@@swethavadrevu9167 have u done this!? How many days,u took?
Excellent neso acadamy is back❤️
I am so GRATEFUL
You can say I'm a "returning student", except that I am no longer inside a class. Thank you sir. Great videos. Keep it up.

Before the day of exam I learn from here😁😁👍👍👍tnx sir
really appreciated your video lecture which caused me to clarify most things in my studies.
I think I'll pass my exams.... Your lecture s are really helpful
In the last example I think you may also add the step in which the DTS is plotted, which is the T value. Refreshing things up here, took these classes a long time ago. Clear and great explanation! Thanks
Actually for a more general view, it would not be necessary, just if more specifics are needed... Let's see, I will run through all the playlist :)
There are two kinds of single depending on the value they take wrt to time
So their names are continuous time signal CTS and discrete time variable TTS
One which take values for every value of time is CTS other which takes value for discrete values of time TTS
CTS representated as x(t) t is independent variable time and x is dependent variable that is signal
TTS is represented as x(n)
X is signal and n is integer
For example the diff in the two consecutive times is T in two consecutive times is 2T in this way we represent it for 1t,2t,3t as for 1,2,3 factor of T is hidden
And for representing purpose in TTS, we place arrow below the value TTS takes for integer 0 that is when time was 0 the value it took
Thank you

Change your laptop
Thank you 🙏
Sir, you talked about DC not being a signal, can you elaborate please? And what about step function, will it also be not categorised as a signal beyond t0?
unit step is a signal because it changes from o to 1 at t=0(discontinuous at zero). but a dc is never changing ,it is always constant for all time t
thank u you sir for your precious work..... many new student of wbut will get benefits
Really ur videos r helping at a lot sir... Ur making the really engineering Students....
Tnqq so much for ur great explanation
Thank you for the video.
Thanku so much for making these videos
It helps a lot
Hello sir ! please explain between x[n] and x{n}. thanks after that
*What if 0 is not in the domain of the discrete time function? Where to put the arrow?*
I too have same doubt. Did you get answer?
I too have same doubt
when you will start at that time time must be zero.so n corresponding to that time always keep a value 0.
much appreciate the efforts!
I came across your channel (.hoped to have found it before..).and now thinking to go through this playlist.. thank you sir 🙏nice explanation
Great knowledge sir thanks I am understanding your lecture
ex:dts=[1,0,1,2,2,1],from left to right sir you tell that second 1 as a x[n] at n=o.But also can take first and last 1 as a x[n] at n=0.why you only take second 1 as a x[n] at n=0?
I have the same query
Sir, please make a video on different types of amplifier.
It will be very helpful.
👍 great
Thanks. Sir your lecture is of worth to learn. ..
Sir, Can you elaborate existence of n? having doubt in that like how you calculate T to 1 and 2T to 2 likewise. Kindly explain that!

very much thanks
Hello Sir, You have explained how n is an integer for uniformly sampled signal then how is n an integer for non uniformly sampled signal.
Please clarify it.
Do you have anything about converting continuous to discrete or plotting frequencies on the pole-zero diagram?
Sir,please upload all the videos of signals and systems...will be very thankful to you
Doubt: in last 10:21. If let's say x[0]=1, how can you tell it's 1 of 3rd in series {1,0,1,2,2,2} it can be 1st one know?
If it's 1st one the data is wrong again!
sir i have a doubt, in the last example of discrete signal , if suppose signal is not given to us how did we got to know that x[n] at n=0 will be 1?
U r a fool if they mention it in the ques then automatically u can generate the signal common sense dude
@Prathipati tejopavan There will be an arrow to the value at n=0 in the given signal x[n].
Thanks 😊
Good explained
Thank you
Very helpful..thnx

Why do we have to remove T? And how did you just remove T like that? Is it by equating T to 1? Can we cancel an independent variable whenever we want to? I don’t understand
Since T is on both the axes, it gets cancelled.
its like taking common and cancelling
Very clear and informative, thanks sir.

In every subject , your lectures are awesome☺️☺️😊
Sir can you give a sugestion me to use which kind of books of s & s
allah razı olsun
These video lectures are great.
But there's one thing, FOR GOD'S SAKE BE A LITTLE LOUDER ..
turn up the volume, please.
Sir how can we say that signal have integer inputs in non-uniform sampled signals?
9:55 u said we simply put an arrow at where amp is 1 we take it as n=0 but y u choose middle 1 insted u take first 1 as n=0 ,i am so confused plz answer me

Can you give me the real world analogy for elementary signals
very confusing actually
Lol
For discrete he explained in time manner then in integer coz its the variable.
I laughed coz i felt u.
Hey Neso Academy, Do you have a Lecture on Discrete-Time Fourier Transform(DTFT)?
In cts graph, you have taken t as x-axis then y you took t as an x-axis for dts also, you should take n?
Dhyan se video dekh bhaiya
I write it.
Sir can u upload the videos of electromagnetic and transmission lines full subject
Hello sir
How come time is negative?
Please respond.
Thank you..
what if my sampling period is not 1 then how do we know x{n}?
it is proper to call it t negative one instead of t minus 1
Sir, When the discrete time signal will be non-uniformly sampled then what notation will be arise?
Period of signal will also vary in case non uniform
sir .. is there any differences in using brackets for instances, for DTS square brackets .. ?
Why should we use [. ] Brackets in discrete time signals sir ?
Sir, as u given that example of {101221} it contain 3ones so how do we get to know that we have to take that 1 not the other one
is mechanical force variation with respect to time is a signal and whether fft and other techniques are applicable to them
Greetings! Sir why we put arrow below the middle 1. Why not for the first 1. To know the value of all signals?
Sir how you cancel out the T here??
Please kindly tell me the term
I don't understand how he cancels T
Sir, please suggest some books.
T is a constant. So T is not gonna change and its not gonna affect the x value. But the integer n affects the T. So we change the representation. I think its a convention to say x[n] bcuz we usually put inside the brackets the variable which affects the value of X , though you can represent the same function as x[nT].
lets say X[y]=10Ty. If Y = n, the X[n] = 10Tn.

In the video of addition of continuous time signal the amplitude is constant b/w two interval if it was a sinusoidal signal or cosinosoidal signal how can we add the signals
Sound is very low
Sir could u tell me how to convert continuous time function to discrete time function.
Actually i need to know how to convert a differential equation in time domain to difference equation in discrete form
Explanation typing on graphs how should we understand
similarly i need for mosfets and transistors
What will be X axis if non-uniform sampling is performed to get a Discrete signal??
Sir how did you know at n is equal to 0 the amplitude is 1 ?? In discrete signal case
Generally we know that time will not exist in negative. But can I know why time is considered negative in the above explanation ??
When u told that,'when n=0,x{n} is 1then why didn't you have chosen the first most value of 1when x(-2)...I mean how did u get to know that we have to chose middle 1 rather than choosing first or last 1
Can this lectures are usefull for gate preparation...?
