How do you calculate N in DFT?

DFT[x1(n) N x2(n)] = X1(k)X2(k) Where N indicates N-point circular convolution. Where N Indicates N-point circular convolution.

What is n-point in DFT?

Definition. An N-point DFT is expressed as the multiplication , where is the original input signal, is the N-by-N square DFT matrix, and. is the DFT of the signal.

What is N in discrete Fourier series?

The Discrete Fourier Series (DFS) is an alternative representation of a periodic sequence x with period N. The periodic sequence x can be represented. as a sum of N complex exponentials with frequencies k2π N. , where.

What is N in N-point fft?

N is the number of points used to calculate the fft, it does not increase physical resolution but adds more point to the spectrum for more visual resolution, N is arbitrary.
