Which of the following is NOT one of the types of amplitude modulation? Correct Answer Single-sideband with carrier

Vestigial Sideband:

VSB (vestigial sideband) transmission transmits one sideband fully and the other sideband partially thus, reducing the bandwidth requirement.

Vestigial Sideband Modulation (VSB) is used for video modulation in TV transmission. 

The spectrum of a vestigial sideband is as shown:

Single Side Band (SSB SC)

  • SSB SC is a form of amplitude modulation where only a single sideband is transmitted and 1 sideband and carrier are suppressed.
  • In advantage of SSB is bandwidth saving and power saving over both conventional AM and DSB SC.

Double Side Band (DSB SC):

  • DSB -SC is a form of Amplitude modulation where only the sidebands are transmitted and carrier is suppressed.
  • The advantage is 66% power saving compared to conventional AM.
