1.How do you
compare PCM with PWM and PPM?
2.A 8-bit ADC with 5 volt full scale voltage samples an analog signal at 1 kHz.
Find the speed of the binary information at the output of the ADC.
3. A linear PCM system uses an 8-bit ADC with 8 v full scale voltage. Find the
dynamic range and the SQNR in dB.
4.In a T1 PCM-TDM system, 24 signals all with the same bandwidth of 4 kHz are
multiplexed after sampling at their Nyquist rate. If an 8-bit ADC is employed
in this T-carrier system, find the speed of the digital multiplexed line.
Assume 8 Kbps overhead for the T-carrier.
5.For each of the following line codes, find the approximate required bandwidth
of a T1 line.
