Physics
An AM transmitter at 27 MHz develops 10 W of carrier power into a 50- load. It is modulated by a 2-kHz sine wave between 20% and 90% modulation.
Determine:
(a) Component frequencies in the AM signal.
(b) Maximum and minimum waveform voltage of the AM signal at 20% and 90% modulation. (25.3 to 37.9 V peak, 3.14 to 60.1 V peak)
(c) Sideband signal voltage and power at 20% and 90% modulation. (2.24 V, 0.1 W, 10.06 V, 2.025 W)
(d) Load current at 20% and 90% modulation. (0.451A, 0.530A)
