a) i) A signal has an r.m.s. value of 8. It is affected by AWGN with a noise standard deviation of √2. What is the SNR, both as a simple ratio and in dB? ii) A sinewave has an amplitude of 10 V. It is affected by AWGN which has a standard deviation of 2 V. What is the SNR as a log measure? iii) A PCM system is designed with 8 different levels. The gap between the levels is 1 millivolt. Work out the noise power and the signal power, given that the signal is a sinusoid with amplitude 4mV. Find the signal to quantizing noise ratio (SQNR) in dB.
