Modulation is defined as a process by which any characteristics of a wave is varied as a function of the instantaneous value of another wave. The first wave which is a high frequency sine wave is known as carrier wave. Second wave is known as modulating wave and the resultant wave is known as the modulated wave.

What is the function of a modulator of car?

Assuming you mean the modulator on an automatic transmission... The modulator help to control the timing of the changing of gears in the tansmission.
