Periodicity of Discrete Time Signal | Fundamental Period of Sum of Periodic signals | 1.8

Periodicity of Discrete Time Signal and how to find the fundamental Period of Sum of 2 Periodic signals is addressed in this video. Also, the video answers What is Discrete Time Periodic Signals and how it is different from continuous time periodic signals, and why the oscillation is in discrete time signals are increasing up to a limit before toggling.

Correction @6:04: for k=2, No = 1, therefore the fundamental integer period is 1.

Can you please suggest some good Book for DSP with topics on FT DFT FFT and IFFT?

Professor, If K= 3 and N=10; K=4; N=8; how to plot the sampled signal?

[amandiperera]

Here, should N be a positive integer? So that K also should be a positive integer.

When w=pi/4, N=8. But sir in the image which you've shown, there are only 6 discrete values. Kindly explain
