Just awed by how much I have continuously been absorbing from this channel... From electronics in my sophomore year all the way to communication systems in my junior year as an ECE student! A simple "thanks" is totally not enough to express my gratitude for making all these informative contents!
I am reviewing electronic and communication engineering notes and knowledge thanks to u. Better than watching stupid movies. Good luck and share more videos with us.
2:12 ~ 4:02 * * * This is a common misconception! A discrete-time signal is discrete with respect to the time (horizontal or x) axis, whereas a digital signal is discrete with respect to its value (vertical or y) axis. Great to have this clarified!
Bro exam is coming so we need more videos in signals. Very fantastic this is need to all students very crispy clear concept. Fantastic marvellous. Need more videos in signals
Great video!but at 8:52 if we integrate between -T/2 and T/2 and divide the energy by T and take limit tends to infinity (just like the definition of power states) we get infinity, I don't think this signal is finite power signal, but the signal at 4:23 is finite power based on the definition. Please rectify if I am wrong
At 8:06 , the energy and power that we are finding using the defined formulas are not equal to the conventional energy and power signals. Here, we use Energy and power to just find the size of signal. so the unit of energy cannot be joules
Why are digital and analog only used for communication system Rather all these signas mentioned below 1-continuous and descrete 2-periodic non periodic 3-energy and power 4-deterministic,random 5-real and complex signal
Why analog signal and digital signal looks like AC signal And analog and digital signal amplitude frequency created at negative y axis Is it sign of change in polarity?
According to you digital signal has only discrete voltage in form of 0/1 whether digital signal passes through 0v to +5v 0 to -5v with change in polarity according to your picture digital and continuous time signal waveform where the amplitudes are in negative y axis
@ 0 or 1 represents the logic levels. But in terms of absolute value(the amplitude) they are two different voltage levels. It can be 0 and 5V. -5V and 5V or 0 and 3.3 V. It can be anything.
sir amplitude can't change its defined as maximum value of y and it remains constant what do you mean when you say anaolog signal are signal that can take any value of amplitude ? @ALLABOUTELECTRONICS
In digital signal, the signals can have finite voltage levels. (e.g 0V and 5V). But in analog signal for the given range (let's say for a 0V to 10 V range), it can have any voltage level between 0 to 10. (e.g 2.34 or 4.51 or 9.78984). So, there is no restriction. There are infinite possibilities. Well how accurately you can measure that signal depends on the accuracy and the resolution of the measuring instrument. I hope, it will clear your doubt.
When we say digital signal we usually have perception that it is varying between 0 to 5V, because all our logic circuits typically works on two voltage level. But it's not always true. When we say a digital signal, it has discrete voltage levels. Its not always necessary to be a positive. One positive and one negative voltage is also considered as digital signal. ( As far as two voltage levels are different) I hope it will clear your doubt. This is very basic but someone may ask in interview.

I didn't get your channel before but now l can only solve my problem by seeing your videos. It's awesome.
Sir, your videos are really helpful to us. You are doing great service by offering tutorials of such high quality. Respect👏
Best explanation about signal classification 👌🏻👌🏻👍🏻
Took a while to find someone explaining it this well, thank you!

One of the best videos on YT
Thank you for the strength of the signal example. Great video!

Thanks for videos ☺️ I understood well 👍
Really amazing!! The content is crystal clear. THANKS. 🤩
I SUBSCRIBED
bro i lost you when you brought in those scary maths formulas on the energy and power signals lol, but thats my fault ,keep up the good work
This vedio was so informative
Thank you !
Sir your videos are awesome please put video about 8051,8085,8086,usart waiting sir
Superbb explanation....thanks a ton...
legendary guy
You can talk about fourier series ?
At 8:06 , the energy and power that we are finding using the defined formulas are not equal to the conventional energy and power signals.
Here, we use Energy and power to just find the size of signal.
so the unit of energy cannot be joules
Very nyc explanation. 😊Thanks
Sir aap indian ho toh app hindi- english mein video bnao taki desh aage badh sake aur China se aage ho jaye😍😍🙏🏼🙏🏼
Hey man, welcome to you.
Thanks a lot brother🤘
very good content
Thanku very much sir 🙏
is it true any aperiodic singal can be converted to periodic woth Fourier series ...
please reply
@6:22 you said the time average is taken at an infinitely large interval but its actually taken over just 1 time period right?
Why are digital and analog only used for communication system
Rather all these signas mentioned below
1-continuous and descrete
2-periodic non periodic
3-energy and power
4-deterministic,random
5-real and complex signal
Nice work
Sir pls do lectures on Control system
Well explained
Why analog signal and digital signal looks like AC signal
And analog and digital signal amplitude frequency created at negative y axis
Is it sign of change in polarity?
Yes, that's a change in polarity of the amplitude. The digital signal has only discrete voltage levels.
According to you digital signal has only discrete voltage in form of 0/1
whether digital signal passes through 0v to +5v 0 to -5v with change in polarity according to your picture digital and continuous time signal waveform where the amplitudes are in negative y axis

@@ALLABOUTELECTRONICS tq sir
Awesome video
In digital signal waveform why the rectangle wave in y acis like sine wave
Thanks a lot..
Excellent

I hope, it will clear your doubt.
Square wave you have shown is not a digital signal but analog. Digital signal can not have -ve value. Plz check.
When we say digital signal we usually have perception that it is varying between 0 to 5V, because all our logic circuits typically works on two voltage level. But it's not always true. When we say a digital signal, it has discrete voltage levels. Its not always necessary to be a positive. One positive and one negative voltage is also considered as digital signal.
