Since DC is constant for all values of time we can take fundamental time at any interval as pie, 2pie etc since it same for all intervals of time. We can consider it is repeating same at every interval.
As the definition says it's the smallest positive value, since DC is the same for all values, whenever we choose our fundamental period we can get a smaller one and so on, As there is no smallest positive value of T. if you take any choice you find another smaller one e.g. 0.1, 0.01, 0.001, 0.0001...etc, so the period is undefined
if periodic function is f, then can we declare f' (differential of f) should also be same for nT0, like in sin function (example taken), since in completing a period, it has same slope, please correct me if I am wrong (with reason)
Hi Neso, Thanks for your tutorials but I am facing one problem. I am able to grasp the concept that you are teaching but when it comes to application of those concepts on questions I am fumbling. Please guide what should be done in order to be able to solve the questions. I am preparing for gate. Any book you would like to suggest from which I can do questions on SAS ? Also will there be more lectures coming in this series or I should look for other options to complete the remaining topics like DTFT, FFT, Digital filters etc ?
Try some more solved examples, so that you will get your doubts clarified and try to make a brief notes wherever you feel difficulty so that you can revise those notes easily
Sir in first lecture u said dc signal is not a signal it's just dc value but in ur presentations everywhere ur saying it's dc signal why 🧐🧐🤔🤔pls respond
Sometimes he says that dc is a value not a signal, sometimes he says that dc is a signal. In this video he says that dc is periodic(which is a property of signals, which means that dc is a signal!!). I think he likes to mess up with the viewers. I asked him to clarify the mystery in 4 different videos about dc. He does not respond. He simply enjoys the confusion he creates.
i went through oppenheim's book and signal and systems from schaum outlines series ( where this video series seems to heavily rely on). Even in these 2 books there is not a clear answer. The books say it is a periodic dc signal but..... I also checked quora answers on this question and it seems to be an never ending debate... Until i find a solid final proof i suppose treat dc value as a signal or not as a signal,periodic or not periodic depending on per case. Although, the confusion remains.
Neso Academy, 'DC is a signal but it does not satisfy the purpose of a signal.'. Good. The purpose of the signal is to convey a desired information from Tx to Rx, i suppose. Does your reply here also mean that it is wrong your claim in digital electronics video series(video 2- what is signal, at 6::23).? Over there you clearly say that DC(Direct Current) is not a signal :). i am not aiming to degrade your work, but to clear the confusion. You make great videos.
your sound quality is not good enough...it is very low...when i see these tutorials,it is really very tough to understand without high volume of my headphn...
Even though we increment the time by 5sec it is remaining same i.e it is not depending on the time As u taught in before lecture if it is not depending on time it is not a signal, but here how could it will be a signal

Excellent video! Two thumbs up to you sir.
You put the fun in fundamental frequency.
Sir, if dc value considered, it has constant value for all the time, that means value does not repeat itself over time, that means it is aperiodic.
At around 11:05, you had mentioned cycles per second for DC values which is 0. Could you please elaborate on what is cycles?
Thank you sir very nice gide & very nice best explain periodic and non-periodic signals teaching video.👍
Since DC is constant for all values of time we can take fundamental time at any interval as pie, 2pie etc since it same for all intervals of time. We can consider it is repeating same at every interval.

11:00 but DC is not a signal, because it is not dependant on any variable, then how can it be periodic signal?
Sir you make one video ..on your introduction..(about life journey)
Please upload a video on Bounded and unbounded systems
if periodic function is f, then can we declare f' (differential of f) should also be same for nT0, like in sin function (example taken), since in completing a period, it has same slope, please correct me if I am wrong (with reason)
God bless u sir

great video! Loved it :D
really easy to understand!! thanks admin
thanks a million
Dc value is periodic in nature...but the period is undefined...dc is a constant value ...and for any T or N it will be periodic
Your language is very easy to understand and concept are easyl understand
Check periodicity of x(n)=2u(n) and x(n)=(-0.3)^n . u(n)
its good to have straight A's
Yep😊
@@sadikmuktar9961 keep staying positive :)
@@nickthewinner2194 Ok
if x(t)=A then it is periodic or non-periodic?
Hi, How the dc value can be periodic if the fundamental time period is undefined.
Is Principal of digital communication (pdc) and signals and systems name of same subject?
Sir i have doubt how dc sig is a periodic signal.
Bcoz in book it is given that dc is aperiodic signal
is any signal have infinite F.P. ? ( If we put infinite value then what will be the type of signal ( d.c. or not)?
D C
Why do we take 2π as the fundamental for To instead of π
Because after 2pie cycle repeats itself
Thx sir
Sir but in earlier lecture u explained that dc is not signal at all
Today i have my backlog exam of this paper, i wish i never have to learn again.
but what will be the period of the constant function if it is peridioc
Sir, Why we're checking whether dc is periodic or not. It is not even a signal acc. to the definition you told us. Right?
Unit of Time period must be in sec or miniute or hours . Dn how T0 = 2pie
I am following neso only ...
Voice is very lovw
thank you for such easy explanation.. sir pls upload videos on energy and power signals also
Why fundamental time period of dc value is undefined ??
When T0=smallest integer
Which is 1 here
Then T0 must be 1 for dc signal
because it can be any value.
Smallest value may not be 1. It can be .01 or .001 or .000001 etc. Thus undefined.
Guys! Sin √2 t is periodic or not plz reply as soon as possible!
Consider infinity
@@shreyasuresh8291 yes periodic
sir why dc signal is periodc explain with neatly sir
next time while you record the videos plz try to increase the volume. .I increase the volume to the maximum but still its barely audible. .
9:21
false, as it donnot have any fundamental Period.
sir videos are gud but plz comeup with new videos fast as soon as possible bcoz .....we hv to study a subject in one semester
Sir in first lecture u said dc signal is not a signal it's just dc value but in ur presentations everywhere ur saying it's dc signal why 🧐🧐🤔🤔pls respond
Waiting
u explain perfectly but speak so fast.
thank u
then decrease the playback speed
how can you say in next lecture !!
That To can not be infinity but if you calculate it in dc from fundamental frequency you will find To zero !!
x[n]=cospad div 3 n + sinpad div 4n
I DON'T HAVE MATLAB ON MY COMPUTER
Periodic
hi
i n the first lecture u said dc is not a signal and then u are using dc value in periodic signal

👍👍
try to use proper mic . bcz sound comes very low
DC signal not a periodic ... Because it does not repeat itself in the Equal interval of time...
i gues the fundamental frequency is 0 because the period is infinite so 1/infinity =0
solve this
sint+sin2t
x(t)= Sin 2t
someone please do this problem, sin is 2 squ
Non periodic signal is not available
Can u explain more clearly please???
gud
Bhai sin ka period toh pi kisine bola bhi nahi
