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 frequency domain (to be added) |
|
Modulating Signal in frequency domain (to be added) |
|
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
