(a) Derive and draw the flow graph to find the radix-2 FFT of an eight point sequence using DIT-FFT algorithm.
Explanation
The flow graph for the radix-2 FFT of an eight-point sequence using DIT-FFT algorithm consists of three stages. Each stage consists of butterflies, each of which performs a specific operation. The output of each stage is fed into the next stage, resulting in a continuous flow of data through the system.
