1. A sine wave is to be used for two different signaling schemes: a. PSK b. QPSK The duration of a signal element is 10-5 s. If the received signal is of the following form: s(t) = 0.005 sin (2 106 t + ) volts And if the measured noise power at the receiver is 2.5 x 10-8 watts, determine the Eb/N0 (in dB) for each case.
