Homework Answers
Steps for Radix – 2 DIF-FFT Algorithm :
1. The number of input samples give N = 2^M , M is an integer
2. The number of stages in the flow graph is M is = log of N to the
base 2
4. Each stage consists of N/2 Each stage consists of N/2
butterflies butterflies as drawn in figure. The expression for
twiddle factor and its exponent K is shown in Picture that I
aploaded below.
Note : All the calculations must be done patiently inorder to get accurate answers. If any mistake happened in some stage it will reflect to next stages also.
