6. Determine the design parameters for an audio system:

a. Determine the total bytes/sec required for an audio signal of 16 bits/ sample per channel, two channels, sampled at 44.1 kHz.

b. Given a clock period P = 20 MHz for a bus, determine the bus width required assuming that non-burst mode transfers are used and D = O = 1.

c. Given a clock period P = 20 MHz for a bus, determine the bus width required assuming burst transfers of length four and D = O = 1.

d. Assume the data signal now contains both the original audio signal and a compressed version of the audio at a bit rate of 1/10 the input audio signal. Compute the total data bandwidth and the bus bandwidth for burst transfers of length four with P = 20 MHz and D = O = 1.
