Model: K3

PHASE MODULATION

K3 0

 

Objectives

  • To demonstrate how a carrier’s instantaneous phase angle is made to vary in proportion to the modulating signal’s amplitude.
  • To demonstrate the effect of frequency deviation. To demonstrate how a carrier’s instantaneous phase angle is made to vary when the signal crosses zero axis.
  • To demonstrate how phase change occurs when the modulating wave changes polarity from + to - and from - to +. To demonstrate why phase modulation is some times called as indirect FM.
