For the following communication system: y(t) DC Block So No n(t) 2 cos(2T fe t) Where: ??? (t)-Ac[1 + cos(2n fn t)] cos(2n fet) n(t)-n(t) cos(2? f t)-ns(t) sin(2n f t) A. Analyze the system and write an equation for the output signal y(t) B. Write the equation for the signal-to-noise ratio at the output. C. Let A,-10 volts,f,-10 kHz, and Mo-10 ?W/Hz. Find the signal-to-noise ratio.
