Modulation
In telecommunications, modulation is the process of varying a Periodic function waveform, i.e. a tone, in order to use that signal to convey a message, in a similar fashion as a musician may modulate the tone from a musical instrument by varying its volume, timing and Pitch .... . The term tuner is used both for part of a radio receiver which also contains an amplifier section and for a boxed piece of equipment to be connected to a separate amplifier.
