Question:
In Section 9.7 we considered a noise analysis of the decimation-in-time FFT algorithm of figure. Carry out a similar analysis for the decimation-in-frequency algorithm of figure, obtaining equations for the output noise variance and noise-to-signal ratio for scaling at the input and also for scaling at the input and also for scaling by ? at each stage of computation.
