Assignment:
A signal a(t) is modeled as a baseband stationary process with bandwidth 5 kHz and probability density function
Pa(u) = 1/2 triang (u/2).
The signal is PCM encoded
a) What is the resulting Aq using a uniform quantizer with 32 levels?
b) What is the ADC bit rate Rb sampling at the minimum sampling frequency?
c) What is the highest Aq achievable for a binary channel with bit rate 80 kbit/s?
d) What is the highest Aq achievable, considering the same binary channel of the previous point, if a guard bandwidth of 1 kHz is required by the anti-aliasing filter?
