Q2. 20pts
The information in analog waveform, with a maximum frequency $f_m = 5 kHz$, is to be transmitted over an M-ary PAM system, where the number of PAM levels is $L = 32$. The quantization distortion is specified not to exceed $\pm 2\%$ of the peak to peak analog signal
a) What is the minimum number of bits/sample, or bits/PCM that should be used in digitizing the analog waveform
b) What is the minimum required sampling rate, and what is the resulting bit transmission rate
c) What is the PAM pulse or symbol transmission rate?
d) If the transmission bandwidth (including filtering) equals 12 kHz, determine the bandwidth efficiency of this system
