What is AM?

Amplitude Modulation is the done by modulating the Amplitude of an sinoid Carrier signal. The Carrier Signal has usually a higher Frequency than the modulating signal.

An Example

Carrier Signal in time domain Carrier Signal in frequency domain (to be added)
Modulating Signal in time domain Modulating Signal in frequency domain (to be added)
AM Signal AM Signal in frequency domain (to be added)

special kinds of AM

  • DSSC, double side band supressed carrier
  • SSB, single side band
  • residual sideband modulation (modulation used for analog TV applications)
  • QAM
