How do you plot a discrete time signal?

A discrete time signal just means sampling your continuous signal at discrete time intervals. The simplest way this can be done is by increasing your step in n. n = [-5:0.25:5]; y = 5*cos(pi*(n/2)-(pi/2));

What is the value of discrete time Xn at n 0?

What is the value of discrete time signal x(n) at n=0 whose Fourier transform is represented as below? Therefore, the value of the signal x(n) at n=0 is ω_c/π.

How do you calculate discrete time frequency?

A discrete-time signal of fundamental period N can consist of frequency components separated by 2π/N radians or f = 1/N cycles.
