Modulation is the use of one electrical signal to “control” a primary variable of another.
For example, if an audio signal voltage is used to control the “amplitude” of a carrier signal, the result is amplitude modulation.HDMI Encoder Modulator,16in1 Digital Headend, HD RF Modulator at Soukacatv.comSKD3013 3 Channel HD Encode ModulatorSKD19 Series 1U Rack 12CH Encode Modulator It is important that you do not confuse “mixing” with “modulation.” Mixing occurs when two (or more) signals are simply combined in a linear network.
AM radio broadcast transmissions contain two signals of primary importance to the user: the carrier signal and the audio signal, or the program signal.
The carrier frequency is the frequency to which the radio receiver is tuned for station selection.
Figure 1 illustrates an amplitude-modulated wave shape as it would appear when picked up by a radio antenna.
When the AM signal was broadcast, the program signal modulated the amplitude, or the level, of the carrier; this process formed an “envelope” of carrier amplitude, having the same shape as the program signal.
