A CB transmitter is rated to supply 4 W of carrier power to a 50 Ohm load while operating from a power supply that provides 13.8 V. The nominal supply current is 1 A without modulation and 1.8 A with 80 % modulation. Calculate the overall efficiency of this transmitter, with and without modulation.
