Angle modulation

Angle modulation. Angle modulation can be divided into frequency (FM) and phase modulation (PM) Both FM and PM are widely used in communication systems The most important advantage of FM or PM over AM is the possibility of improved signal to noise ratio. Frequency modulation. Frequency.
