A DAT-recorded digital audio signal is to be broadcast

A DAT-recorded digital audio signal is to be broadcast digitally. Using the Kaiser method, design a sampling rate converter filter for down-converting the 48 kHz DAT rate to a 32 kHz broadcast rate. What is the filter’s cutoff frequency? Assume reasonable values for the filter’s transition width and stopband attenuation. What is the filter length N? What is the computational cost in MAC/sec assuming a polyphase realization? Write explicitly (i.e., in the form of Eq. (12.6.10)) the sample processing algorithm implementing the conversion algorithm.
