How do you find the periodicity of a discrete-time 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).
What is the periodicity of the signal?
A periodic signal is one that repeats the sequence of values exactly after a fixed length of time, known as the period. In mathematical terms a signal x(t) is periodic if there is a number T such that for all t Equation 10.10 holds.
How do you calculate periodicity of a signal?
As mentioned above, the period of a periodic signal is called T0, and it is the smallest positive value of T that makes the equation x(t) = x(t+T) true for all t. The period of a signal is sometimes called one cycle of the signal.
What is the periodicity of a discrete-time signal Mcq?
A discrete-time signal is periodic if there is a non-zero integer N ∈ discrete-time such that for all n ∈ discrete-time, x(n + N) = x(n). The smallest value of N is known as the fundamental period.
