How many stages are there for 8 point DFT Expalin with proper example?

There are three stages in computation of 8 point DFT. In the first stage four 2 point DFTs, in the second stage two 4 point DFTs and in third stage one 8 point DFT are computed.

What is K and N in DFT?

The discrete Fourier transform of a finite-length sequence x(n) is defined as. X(k) is periodic with period N i.e., X(k+N) = X(k). Inverse Discrete Fourier Transform (IDFT): The inverse discrete Fourier transform of X(k) is defined as. For notation purpose discrete Fourier transform and inverse Fourier transform can be.

How do you calculate DFT coefficient?

The DFT formula for X k X_k Xk​ is simply that X k = x ⋅ v k , X_k = x \cdot v_k, Xk​=x⋅vk​, where x x x is the vector ( x 0 , x 1 , … , x N − 1 ) .
