3. a. b. Derive a decimation-in-time FFT algorithm for a 12-point DFT, and draw a complete flow diagram for the algorithm. Calculate the approximate number of complex operations required to compute the 12-point FFT and compare with the number of complex operations required to compute the 12-point DFT directly. 3. a. b.
