A binary encoded signal has a bitrate of Rb 28 kbps An Alte

A binary encoded signal has a bit-rate of Rb = 28 kbps. An Alternate Mark Inversion 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? B = 112 kHz B = infinity B = 28 kHz B = 56 kHz B = 14 kHz B = 7 kHz

Solution

Speed or bit rate = nf_s = R_b

Bandwidth minimum is R_b/2

Bandwidth maximum is R_b

Normally bandwidth consider to be half of speed

Bandwidth = 28/2

Bandwidth = 14 kbps
