An audio message m(t) with a single-sided bandwidth of 8000 Hz and maximum amplitude of 4 Volts is to be modulated and transmitted wirelessly via antenna: If this message is transmitted as the following DSB AM signal: y(t)= 7[1 + K_am(t)]cos(2, 052,000 pi t) Find the following: i. The bandwidth of the modulated signal, y(t). ii. The value of K_a required to obtain a modulation index of beta = 0.8. iii. The power of the message signal, m(t) (assume m(t) is a sinusoid for this). iV. The power of the carrier signal. v. The power of the modulated signal, y(t).
