A sinusoid x(t) = Am cos(2? fmt) modulates a sinusoidal carrier Ac cos(2? fct) in a double-sideband transmitted-carrier (DSBTC) system of the type illustrated in Figure E-12. If Am = 1, fm = 10, Ac = 4, fc = 1000 and m = 1, find the numerical value of the total signal power in y(t) at the carrier frequency Pc and the numerical value of the total signal power in y(t) in its sidebands Ps .
