Answer:

channel capacity for a teleprinter channel is 474.76 bit per sec

Explanation:

given data

bandwidth = 300 HZ

signal-to-noise ratio = 3 dB

solution

we use here decibel formula that is

SNR(dB) = 10 × log (SNR)   ..............1

here SNR is signal-to-noise ratio

so put here value we get

3 = 10 × log( SNR)

SNR = [tex]10^{0.3}[/tex]  = 1.995

and now we use here Shannon equation that is

C = B × [tex]log_2[/tex] ( 1+SNR)   ...............2

here C is channel capacity

put here value and we get

C =  300 × [tex]log_2[/tex] ( 1+ 1.995 )

C = 474.76

so channel capacity for a teleprinter channel is 474.76 bit per sec
