- In this video, the classification of the signals from the communication engineering perspective is explained with examples.
By watching this video, you will learn the following topics:
0:00 Introduction
0:57 Continuous-time signal and Discrete-time signal
1:48 Analog and Digital Signal
4:06 Periodic and Aperiodic Signal
4:52 Energy and Power Signal
9:26 Deterministic and Random Signal
Classification of Signals:
In the general the signal can be classified in the following categories:
1) Continuous-time signal and Discrete-time signal
2) Analog and Digital Signal
3) Periodic and Aperiodic Signal
4) Energy and Power Signal
5) Deterministic and Random Signal
1) Continuous-time signal and Discrete-time signal
Continuous-time signal:
If the signal is specified for every value in time then it is known as the Continuous-time signal
Discrete-time signal:
If the signal is specified only for discrete-time instances then it is called Discrete-time signal.
2) Analog and Digital Signal:
Analog Signal:
A signal whose amplitude can take any value in the continuous range is the analog signal.
Digital Signal:
A signal whose amplitude can take only a finite number of values is the digital signal.
3) Periodic Signal and Aperiodic Signal
Periodic Signal: The signal which repeats itself after some finite time is known as a periodic signal.
4) Energy and Power Signal:
The signal with finite energy is known as the energy signal while the signal with finite power is known as Power Signal.
The signal could be either an energy signal or a power signal, but it can't be both at the same time.
There are some signals (e.g ramp signal) which are neither energy nor power signals
5) Deterministic and Random Signal:
A signal whose physical description is known completely either in mathematical form or graphical form is known as the Deterministic Signal.
A signal which is known only in terms of the probabilistic description like mean, mean square value, and distributions is known as the Random Signal.
In this video, the classification of the different signals is explained with examples.
This video will be helpful to everyone in understanding the classification of the signals.

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.
Took a while to find someone explaining it this well, thank you!
Sir, your videos are really helpful to us. You are doing great service by offering tutorials of such high quality. Respect👏
Thank you for the strength of the signal example. Great video!
I didn't get your channel before but now l can only solve my problem by seeing your videos. It's awesome.
Best explanation about signal classification 👌🏻👌🏻👍🏻
Really amazing!! The content is crystal clear. THANKS. 🤩
I SUBSCRIBED
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
Thanks for videos ☺️ I understood well 👍
One of the best videos on YT
This vedio was so informative
Thank you !
Superbb explanation....thanks a ton...
Best explanation about signal classification
Very nyc explanation. 😊Thanks
Thanks a lot brother🤘
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
Thanks a lot..
Thanku very much sir 🙏
very good content
Awesome video
Well explained
Excellent
You can talk about fourier series ?
Sir your videos are awesome please put video about 8051,8085,8086,usart waiting sir
Nice work
Thanks 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?
Thanks
Sir pls do lectures on Control system
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
Sir aap indian ho toh app hindi- english mein video bnao taki desh aage badh sake aur China se aage ho jaye😍😍🙏🏼🙏🏼
Well
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.
Control systems .videos send sir .
From basics .please sir

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. ( 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.
Hi bro
Sir please do videos in telugu language
Thank you for the strength of the signal example. Great video!
