How do you find the periodicity of a discrete signal?
A discrete-time signal is periodic if there is a non-zero integer p ∈ DiscreteTime such that for all n ∈ DiscreteTime, x(n + p) = x(n). x(n) = cos(2π f n).
Which condition is used to check the periodicity of discrete-time signals?
Discrete Time Aperiodic Signal
If the condition of periodicity is not satisfied even for one value of n for a discrete time signal x(n), then the discrete time signal is aperiodic or nonperiodic.
How do you find the periodic time of a signal?
If x(t) is periodic with period T, it is also periodic with period nT, that is: x(t) = x(t + nT). The minimum value of T that satisfies x(t) = x(t + T) is called the fundamental period of the signal and we denote it as T0.
