An AM signal has the equation:
v ( t ) = [15 + 4 sin (44 × 10 3 t ] sin (46.5 × 10 6 t ) V
(a) Find the carrier frequency.
(b) Find the frequency of the modulating signal.
(c) Find the value of m.
(d) Find the peak voltage of the unmodulated carrier.
(e) Sketch the signal in the time domain, showing voltage and time scales.
