A the antenna current of an am broadcast transmitter, Ask an Expert

Engineering

a. The antenna current of an AM broadcast transmitter, modulated to depth of 40% by an audio sine wave is 11 amp. It enhances to 12 amp as a result of simultaneous modulation by another audio sine wave. What is the modulation index because of this second wave?

b. Sketch the block diagram of phase cancellation SSB generator and define how the carrier and unwanted sideband are suppressed. What change is essential to suppress the other sideband
