Modulation

by TheChas In reply to Modulation

In basic terms modulation is the imposition of one signal upon another.

AM radio uses Amplitude Modulation.
The level of the carrier (base) frequency changes with the level of the signal (music voice) applied.

FM radio uses Frequency Modulation.
The carrier frequency changes in proportion and at the same rate as the signal applied.

There is also Phase, and Pulse modulation.

In most computers the power supply is a switching power supply. Switching power supplies use pulse width modulation in proportion to load to regulate the voltage outputs.

The most common use of modulation in PCs is the modem (MOdulater DEModulator).

Sounds as if the chas hit that one, except that he didn't mention that the modulator driver will be included in your sound device software driver disc
