EE342 Problem Set 10

DUE F 04/23/99

1. Recompute the DFT of the bird chirps using matlab's fft() function. Plot the magnitude spectrum versus frequency in Hertz and comment on any changes in computational speed as well as differences between these results and the results obtained from your dft() function. Remember for optimum performance use a power of two for the number of data points - do a help on fft() to see how to automatically zero pad your data to get a power of two.
