Angle Modulation

• Generalized Angle Modulation

  The angle of the carrier

  

  is

  

  There are two main characteristics of the angle: the instantaneous phase of the carrier is

  

  and the instantaneous frequency of the carrier which is

  

  the first term is the carrier frequency and the second term represents a change in the frequency from . It is called the instantaneous frequency deviation.
