How do you find the frequency of a discrete-time signal?
A discrete-time signal of fundamental period N can consist of frequency components separated by 2π/N radians or f = 1/N cycles.
Which transform is only for discrete-time?
Definition. The discrete-time Fourier transform of a discrete sequence of real or complex numbers x[n], for all integers n, is a Fourier series, which produces a periodic function of a frequency variable.
What is the highest Normalised frequency of the output 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.
