Показать описание
Signals and Systems: An important point related to Periodic and Non-Periodic Signals.
Topics Discussed:
1. Revision of periodic and non-periodic signals.
2. Revision of condition for periodicity.
3. Understanding why repetition of a particular structure from infinity to minus infinity is a must for any signal to be periodic.

Sir, your videos helps finantially poor average students to acquire great command over the subject for free, Really very thankfull... God bless u😘

Sir, how we calculate fundamental period of discrete signal have given formula for it but not any example for it ....plz solve 1 or 2 problems for discrete signal as

Sir even though the signal is shifted but the time period is same for both x(t) and x(t+0.5) does it not called periodic signal if not correct me??

u finished at 6 minutes clearly
my teache r takes a month for this

but if we add that condition, doesn't it make the signal into a CTS? since it's from -infinity to infinity...

Fundamental time period should not be infinity..but for dc signal it is infinity and in previous video you told dc signal is periodic sir..please confirm

sir ur neso site is not working properly..when i went hw problems it seems to be something went wrong

Sir but the values are same at each time. From -1.5 to 0, there are same number of curves... Then how can we say that they are not same

You are such a great teacher, but you need to show the other side of what ever you are explaining. Show us a graph satisfying the condition of periodic signal from negative infinity to infinity too pls.

Cos (πn^2/8) periodic or aperiodic?
how to justify that it is aperiodic?

there are 6 shape in both the graph from minus infinity to plus infinity so it shoud be periodic
