Question

Electrical Engineering

By using MATLAB

1. Divide a speech signal or music signal into frames of size N= 64.
2. Compute the N?point DFT of each frame.
3. Save only first L = 20 DFT coefficients.
4. Reconstruct the frame from these L coefficients. (Do not disturbthe symmetry
of DFT during inverse DFT computation. X[k] = X[N ?k] for realsignals, N = 64
here. Pad zeros for missing DFT coefficients.)
5. Comment on the quality of reconstructed and the original speechsignal.
6. What is the effective data compression ratio? Note that DFTcoefficients may be
complex valued!
7. Repeat the above experiment for L = 10 and L = 5.
