How do you find the frequency of a discrete signal?
A discrete-time signal of fundamental period N can consist of frequency components separated by 2π/N radians or f = 1/N cycles.
What are different signals used for analysis of discrete time signal?
The standard discrete time signals are discrete time sinusoids, unit sample sequence, unit step signal, unit ramp signal and exponential signal etc. which are very useful in the analysis of discrete time systems.
What is the maximum frequency of discrete time signal?
(2) shows that a signal with frequency π is an alternating signal, so ω=π clearly is the maximum possible frequency of a discrete-time signal.
How do you plot discrete time signals?
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));
