  3. 1) 16-level signalling is equal to 4 bits per sample, hence the sampling rate is: 5/4 = 1.25 MHz So the theoretical min. system bandwidth, by Nyquist theorem is given by: 1.25/2 = 0.625 MHz 2) Excess bandwidth = 0.8 - 0.625...

  4. Consider the wall before the duct is inserted, 25 = 10.log(1/Tw) where Tw is the transmission coefficient of the wall hence, Tw = 3.162 x 10^-3 After the duct is placed, 20 = 10.log(1/Tc) where Tc is the new transmission...
