MATLAB program of expansion and compression of signal
This MATLAB program expands and compresses a sample signal using a scaling factor of 2. The original signal is plotted, then compressed by multiplying by 2 and expanded by dividing by 2. The compressed and expanded signals are plotted alongside the original for comparison. The program displays the original, compressed, and expanded signal values.
