What is 8 point FFT?

8 point radix-2 DIT-FFT: FFT is an algorithm to convert a time domain signal to DFT efficiently. FFT is not unique. Many algorithms are available.

How many stages are there in 8 point DFT?

3.2 Three stages in the computation of an N = 8-point DFT.

What is a butterfly in DFT?

In the context of fast Fourier transform algorithms, a butterfly is a portion of the computation that combines the results of smaller discrete Fourier transforms (DFTs) into a larger DFT, or vice versa (breaking a larger DFT up into subtransforms).

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.
