Solution: An FM transmitter outputs 1 kW of power when modulated by a 3 kHz sinusoid

Solution: For a modulation coefficient m = 0.2 and an unmodulated carrier power Pc = 1000 W

Solution: Determine the power in the sidebands as a percentage of the total power

Solution: What is the total sideband power radiated?

Solution: Determine the power content of each of the sidebands and of the carrier

Solution: Find the power efficiency of an AM wave for a modulation index of 0.3

Solution: What will be the percentage savings if the carrier is suppressed

Solution: What would be the percentage power saving

Solution: How much of this is the sidebands power?

Solution: Calculate the total power supplied by an AM transmitter
