The world of IBOC encompasses AM and FM operation. At the present time, AM and FM IBOC operation is in use by a number of stations. The use of AM IBOC at night is still under discussion due to a ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...
