Q3.a. A system carried 32 voice signals where multiplexed and modulated by PCM, if the maximum and minimum values of the messages is 70 v,20 v; respectively, with maximum quantization error is 0.125, and sampling frequency 8KHz: i. Find the transmission bandwidth. ii. Sketch the PCM signal for second sample of the first signal, if the value of the sample at this moment is 25v. iii. If quantization error becomes 0.25, What are changes will happen in the system design? b. a PCM system uses a uniform quantized followed by 50Mb/s bit rate, with fs = 1.5MHz, how many sinusoidal message signals can be transmitted where the SQNR for each message shall not be less than 43.9dB.
