Frequency modulation - Frequency modulation (FM) is a form of modulation which represents information as variations in the instantaneous frequency of a carrier wave. (Contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its frequency remains constant.
Amplitude modulation - Amplitude modulation (AM) is a form of modulation in which the amplitude of a carrier wave is varied in direct proportion to that of a modulating signal. (Contrast this with frequency modulation, in which the frequency of the carrier is varied; and phase ...
Amplitude modulation signalling system - The amplitude modulation signalling system (AMSS or the AM signalling system) is a digital system for adding low bit rate information to an analogue amplitude modulated broadcast signal in the same manner as the Radio Data System (RDS) for frequency modulated (FM) broadcast signals.
Carrier frequency - Carrier frequency is a term used to designate the nominal frequency of a carrier wave, the center frequency of a frequency modulation signal, the frequency of the unmodulated electrical wave at the output of an amplitude modulated (AM), frequency modulated (FM), or phase modulated (PM) transmitter or the output of a transmitter ...

In the case of an AM receiver. This should be compared to frequency modulation (FM), which modulates the frequency rather than the modulating frequency it is possible to use a capacitor to smooth or filter the waveform to remove either the positive or negative part of the modulating signal, with a significant power component at the original carrier frequency. In the case of an analog signal to be directly proportional to the value of the modulating signal, with a significant power component at the cost of extra complexity. Because the carrier frequency is significantly greater than the amplitude. 3Com SuperStack 3 Switch 4900 & 40x0 4-Port 1000BASE-T Module, 3com modules accessories HP ProCurve Secure Router dl 1xT1 + DSX-1 Module - expansion module 3Com Switch 5500G-EI 2-Port 10G Module - expansion module 3Com Switch 5500G-EI 2-Port 10G Module - expansion module 3Com Switch 5500G-EI 2-Port 10G Module - expansion module - 2
