An unmodulated carrier of amplitude A c and frequency c and band-limited white noise are summed
Question:
An unmodulated carrier of amplitude Ac and frequency ƒc and band-limited white noise are summed and then passed through an ideal envelope detector. Assume the noise spectral density to be of height N0/2 and bandwidth 2W, centered about the carrier frequency ƒc. Determine the output signal-to-noise ratio for the case when the carrier-to-noise ratio is high.
