An AM transmitter at 27 MHz develops 10 W of carrier power into a 50-Ω load. It is modulated by a 2-kHz sine wave between 20 and 90 percent modulation. Determine:

(a) Component frequencies in the AM signal.

(b) Maximum and minimum waveform voltage of the AM signal at 20 percent and 90 percent modulation. (25.3 to 37.9 V peak, 3.14 to 60.1 V peak)

(c) Sideband signal voltage and power at 20 percent and 90 percent modulation. (2.24 V, 0.1 W, 10.06 V, 2.025 W)

(d) Load current at 20 percent and 90 percent modulation. (0.451A, 0.530A)
