Question: 1 a binary baseband system operates at a data rate...

Question details

1. A binary baseband system operates at a data rate of 10 bits/sec in a channel with additive white Gaussian noise (AWGN) of power spectral density No-0.25x103 W/Hz. Given that the binary source signals are equally likely and the transmitted pulses are of the form si(t) if1 sent where the pulses so(t) and si(t) are shown below
