In discretetime signal processing, it is often necessary to convert a signal from one sampling rate to another. A common example is the conversion from the sampling rate of a compact disk (CD); signal (44.1 KHz) to that of a Digital Audio Tape (DAT) signal (48 KHz). Another example is the aud io standard in HighDefinition Television (HDTV) transmission, where at least three sampling rates are supported (32, 44.1, and 48 KHz). Although in principle we may convert the signal back to analog form and resample at the desired rate, it is usually preferable to perform t he entire conversion digitally. This is clue to many considerations including the fact that conversion to analog form often introduces noise in the signal, and that digital signal processing can be much more costeffective and flexible. This MATLAB project asks you to perform a sampling rate conversion on segments of audio signals. The input audio signals are quantized to 8 bits and sampled with a sampling frequency of 11,025 Hz. You are required to convert the signal to a sampling rate of 24,000 Hz in a computationally efficient manner. Although one conceptual way of realizing this sampling rate conversion process is to upsample
