Problem
An amateur-radio transmitter delivers a total power of 50W into its antenna, amplitude-modulated by a single audio tone to a modulation index m=0.6.
((a)) Calculate the fraction of the total power carried in the two sidebands.
((b)) Calculate the power in the carrier.
((c)) Calculate the power in each sideband.
