thank you so much for these lectures. You are explaning everything baby steps. These are the lectures that uni. prof. lecturers should actually tell like this.
If we know axis transformation ... Then we find that 'shortcut' method is just a replica of Method 2( as mentioned in video). In that 'shortcut' if we first divide time axis by 2 then add 1.5 .. it would be equivalent operation as discussed in Method 1( as mentioned in video).
I have found your presentations on Signals and Systems very refreshing. Is there a particular workbook you are using as you are referring to problems in a workbook. Any advice would be greatly appreciated
There was no necessity of explaining some things (about choosing examples), But u still made my time for it, and that me to spend a moment for appreciating. Alos ,Thank you for this free and best content.
please sir complete signal system syllabus as soon as possible full syllabus thank you sir ! i want to clear my basic concepts perfectly so that I can join coaching for GATE !
What if I take it like this x(2(t+3/2)) Then order of priority of Shift > Scale > Invert Then, first shift to the left by 3/2 to get new interval of -2.5 and 1.5 Finally, scale with 2 to get -1.25 and 0.75 Not the same answer as yours. What did I do wrong?
Even i had the same doubt the answer is we are not shifting the signal we are shifting the time axis Delaying the signal corresponds to right shift which is same as advancing the time axis keeping the signal in the same place Hope u got it
Could you point me to a good book I could study with? Better if it has solutions manual. I want to solve problems but I also want to know when I'm getting them right or wrong
sir ,I could not understand that in second method when there is t+3 then how did we get -4 in x axis , we are adding 3 , it should be -1+3=2, like in shortcut method we are subtracting 3 so -1-3=-4 that's correct
Sir i think is problem ka solution galat hai kuy ki u says in previous lecture of time scaling ki 2 ko time ke sath multiple karo agar mode of alfa >1 but in 1 st step u divided it
why dont u take any example , rather than just teaching the concept include some examples of every single topic so it will be more easy to clear the concept

8:23 - 8:27 , according to my understanding, without separating time factor, the wrong answer will be of amplitude 1 over -3.5 to -1.5.
Yeah.. I too think ur ans is crt and video it's wrong..
@@rachanat9603 no The original signal was x(3)=1 & x(-1)=1
Exactly
you saved my academic life sir... thank you!
Thanks you so much for this kind of explanation in s and s with sort , easy and polite manner

Arey yaar itne achese bolne par bhi kyo dislikes marte I don't I just loved the session sir keep on rocking sir
Your videos are love ❤😘 with Peace... Excellent work💼
GOD BLESS YOU INDIAN GUYS MEEEHN!! :D
Thanks, it cleared all my piled up doubts
Extremely helpful! thank you, Sir! It would be great if you have PDF Notes of your work!
Perfect explanation
good explanation

x(2(t+3/2))
Then order of priority of Shift > Scale > Invert
Then, first shift to the left by 3/2 to get new interval of -2.5 and 1.5
Finally, scale with 2 to get -1.25 and 0.75
Not the same answer as yours. What did I do wrong?
Thank u so much sir🙏
thank you raising volume
great explanation
Awesome
Thank you
Awesome trick really
At 12:10
How come negative time shifting make the signal move left ward..
Also at 13:10
How come expansion Time scaling made the signal to contract...
WHEN WE REVERSE A SIGNAL THEN SHIFTING IS DONE IN THE OPPOSITE DIRECTION
we're not negative shifting. we're changing the axis from t+3 to t. that's different.
Even i had the same doubt
the answer is
we are not shifting the signal
we are shifting the time axis
Delaying the signal corresponds to right shift which is same as advancing the time axis keeping the signal in the same place
Hope u got it
well explained
Sir at time scaling u did mul operation for compression and division for expansion and sir now why we use division for compression
Can you only time shift to the left?
Could you point me to a good book I could study with? Better if it has solutions manual. I want to solve problems but I also want to know when I'm getting them right or wrong

Thanks for short cut method 😍
M-III ROCKS😭😭😭
Very nice sir
Typing of lecture words is not correct. the text is coming on the diagrams which makes the understanding very very difficult.
Great
Thank you sir..however what if there was negative amplitude scaling? How to deal with that?
Ghaz T flip signal about time (t) axis.
sir please make a presentation on sequence generators in digital electronics
Why shouldn't we consider x(2t+3) as x(2(t+3/2)) and perform shifting and scaling
here the time axis is (2t+3) not t ... so any operation will reflect on (2t+3)
Sir at 11:35 in m3 how can we take the same graph .... i dint get that one sir
sir ,I could not understand that in second method when there is t+3 then how did we get -4 in x axis , we are adding 3 , it should be -1+3=2, like in shortcut method we are subtracting 3 so -1-3=-4 that's correct
Me too
@@ashfaqurtahashin564 see actual question was -3 and 3 ...
Why we divided by 2?
i cant use this method for discrete signal
sir, are this type of questions are import in GATE exam
Where the 2 from x(2t+3) coming from?
in shortcut method why we con not subtraction form 0 ????
Tell us your name bro r u indian ??
I like u Sir
In time scaling and amplitude scaling how we'll get to know that we to compress or expand
u dont saY NIBBA
Multiplying by t entails shortening the waveform, whereas dividing t by some number expands the waveform.
Thank u so much sir
Can i know your name sir jii
Sir i think is problem ka solution galat hai kuy ki u says in previous lecture of time scaling ki 2 ko time ke sath multiple karo agar mode of alfa >1 but in 1 st step u divided it
But to plot the waveform he told to divide each time duration by alpha..compression happens... revise it once again....
Sir if we consider it as x(2(t-3/2)) we get a different answer. Why is that?
You have taken negative sign. Take positive sign then answer will come
why dont u take any example , rather than just teaching the concept include some examples of every single topic so it will be more easy to clear the concept
sir: 8 :04 time shift will be towards positve side cuz we have +3 ?

Watch this vedio...
That may clear your doubt..
mujhe nahi samajh me aa raha
in method no 1 u will not perfoming reversal ?
Böyle anlatan hoca oldu da biz mi sevmedik bu dersi.
you have done wrong
@@nesoacademy no , it's sorted now
@@ArpitDhamija I too got same doubt.. Can u clarify
