Include the answer in your writeup. 2.1.2 Bit-Reversed Indexing Some FFT algorithms … WebThe recursive nature of the Sliding DFT algorithm means that some initialization method is required. The output X f,k+1 is only valid if X f,k was valid, and each output relies on inputs from N previous samples. There are two common methods for initializing the algorithm: 1. Cycle zeroes in to flush the delay lines before cycling in data.
