Problem 2: 25 Points The message signal m(t)=2cos(280t) along with the carrier signal c(t)= 2cos(21200t) are applied to a modulator that generates the double sideband suppressed carrier signal s(t). The demodulator is as shown in the figure below. It consists of a multiplier followed by a low pass filter, where the locally generated signal is c(t)=2cos(2(1210)t) and the bandwidth of the low pass filter is 100 Hz. a. Find the bandwidth of m(t). b. Find the time-domain expression of the modulated signal s(t). c. Find the signal y(t) at the demodulator output
