A source produces binary data at the rate of 10 kbps. The source output is transmitted using two modulating schemes, namely BPSK and OOK. Let B1 and B2 be the bandwidth of the input pulses is 10 kHz, we have
1
\({{{B_1}} \over {{B_2}}} = 1\)
2
\({{{B_1}} \over {{B_2}}} = 2\)
3
\({{{B_2}} \over {{B_1}}} = {1 \over 2}\)
4
\({{{B_2}} \over {{B_1}}} = {1 \over 4}\)
