The message signal m(t) has a bandwidth of 30 kHz, a power of 16 watts and a maximum amplitude of 6 volts. It is desirable that this message is transmitted to the destination via a channel with an attenuation of 80 dB and an AWGN with a single-sided noise power spectral density 0 = 2×10-12 W/Hz. The SNR at the demodulator output is required to be at least 50 dB. %3D Tx Kanal Rx m(t) Pr P=S I oss = 80 dR So/N. = 50 dB What is the required transmit power ( Pt ) and channel bandwidth ( B ) if the following modulation scheme is used: a.

Transmitter: a carrier frequency of 108 kHz and a modulating frequency of 3.4 kHz is plied to an amplitude modulator. The USB and the LSB are both transmitted to the distant eceiver, with a suppressed carrier. Receiver: the resultant USB and LSB from the transmitter are input to an amplitude demodulator. A carrier frequency of 108 kHz is reintroduced to the demodulator. Determine the following: 1. The LSB and USB at the output of the modulator. 2. The LSB and USB at the output of the demodulator.
