How do you calculate N point 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 2 point DFT?

Two-point. The two-point DFT is a simple case, in which the first entry is the DC (sum) and the second entry is the AC (difference). The first row performs the sum, and the second row performs the difference.

What is DFT and inverse DFT?

The discrete Fourier transform is an invertible, linear transformation. with denoting the set of complex numbers. Its inverse is known as Inverse Discrete Fourier Transform (IDFT). In other words, for any , an N-dimensional complex vector has a DFT and an IDFT which are in turn. -dimensional complex vectors.
