A signal with a bandwidth of B=10 kHz is sampled at the Nyquist rate and is PCM

Question

A signal with a bandwidth of B=10 kHz is sampled at the Nyquist rate and is PCM encoded with 2 bits. What is the minimum required bandwidth needed for a channel to transmit this new signal? A 80 kHz B 20 kHz C 40 kHz D 5 kHz A binary encoded signal has a bit-rate of Rb = 56 kbps. A Uni-polar NRZ line-code is used to encode these bits for baseband transmission over copper wire. What would be the transmission bandwidth required to transmit this signal? A 56 kHz B 28 kHz C 14 kHz D 112 kHz A binary encoded signal with a bit-rate of Rb = 56 kbps is now encoded using Polar NRZ baseband encoding and then modulated using binary PSK. What is the bandwidth required to transmit this modulated signal? A 112 kHz B 224 kHz C 56 kHz D 28 kHz
