what is the formula for modulation frequency. Df 75 KHz fm 500 Hz BWFM 2 75 5001000 KHz 1510 KHz. I am going to use w which is radians per second w 2 pi f f is the frequency in Hertz.

In the equation above f is the frequency deviation which represents the maximum frequency difference between the instantaneous frequency and the carrier frequency. DT S T S dM T S 4 M T S. Solving the two expressions the modulated wave is represented as.
Calculate the modulation index m f.
I t vsin 2f i t The carrier signal is represented as. In fact the ratio of f to the carrier frequency is the modulation index. This index v is thus defined by the equation The integrated message signal can be represented as. Solving the two expressions the modulated wave is represented as.
