Periodicity of a signal
WebI need to find the periodicity of the following signal: $$ x\left [ n \right ] = \cos \left(\frac{\pi n^{2}}{8}\right) $$ Now I understand that the basic procedure to determine the periodicity is to find a $ N $ such that $$ x\left [ n \right ] = x\left [ n + N\right ] $$. I applied the procedure to the aforementioned signal and got the following results: WebMay 22, 2024 · A periodic function can be mathematically defined as: (7.1.1) f [ n] = f [ n + m N] ∀ m: ( m ∈ Z) where N > 0 represents the fundamental period of the signal, which is the …

WebDec 8, 2024 · Generally, a discrete signal x (n) is said to be periodic with periodicity N, if x (n) = x (n+N) for all values of n. Here u (n) seems to be periodic with N = 1 for all values of n. Yet u (n) is not completely periodic. As you can see, for n = -1, the periodicity lost, as u (-1) is not equal to u (0). It would have been periodic, if all samples ...
