FM Modulation

by mmadejster


Interesting  thing happens when you feed output of the one oscillator into the other oscillator , we obtain new kind of synthesis, what is referred to as  a FM Synthesis or FM modulation.

In the above example, the sine wave(the big one) is modulated by the square wave (the tiny one), So on this case the Sine Wave is the   carrier, and the Square wave is the modulator.

The complex sounds are formed by so-called sidebands, that are created above and below the carrier signals.

In this session  3 sine oscillators are connected in series  have been modulating each other. More  precisely 3 analog filters self-oscillating. The Blue is the FM modulation,Self oscillationI have uploaded video of the FM Modulation of my system.
