Direct-conversion receiver — A direct conversion receiver (DCR), also known as homodyne, synchrodyne, or zero IF receiver, is a radio receiver design that demodulates the incoming radio signal using synchronous detection driven by a local oscillator whose frequency is… … Wikipedia
Frequency modulation — See also: Amplitude modulation In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its… … Wikipedia
Preemphasis improvement — In FM broadcasting, preemphasis improvement is the improvement in the signal to noise ratio of the high frequency portion of the baseband, i.e., modulating, signal, which improvement results from passing the modulating signal through a… … Wikipedia
