Consider a DSB-SC modulator whose input carrier is 2 cos ot. Find an expression for OpsB(m), the spectrum of the modulated signal if the message signal is (a) m(t) = II () + 1(). (b) m(t) = sin e(). In each case, the carrier frequency is !! much greater than the message signal bandwidth. Consider a DSB-SC modulator whose input carrier is 2 cos ot.
