If a carrier signal vc(t) = 10 sin (20000πt+π/2) volts is amplitude modulated by message vm(t) = 8sin(450πt+π/2), sketch the frequency plot for the resulting AM signal and calculate the transmission bandwidth. Write the expression for the AM signal. If the resulting AM signal is viewed on a CRO, what will be the values of Vmax and Vmin? Also sketch the AM signal in CRO and state whether the signal is under modulated / critically modulated / over modulated; justify your answer.
