AM and FM Interactive Resources

Try these interactive resources for investigating how Amplitude Modulation (AM) and Frequency Modulation (FM) works....








The following resources require Java to be installed o­n your computer. Java Software is avaiablefor downloading at  http://www.java.com/en/download/manual.jsp

Some of these resources go well beyond the requirementsfor GCSE. However, the visual effects/demonstrations can be very useful for reinforcing the principoles of AM and FM

AM/FM  This applet covers both AM and FM using the modulating signal, alongside the  modulated carrier wave. Straightforward demonstration   Applet 1

The following applets may also be useful at GCSE although some are more complex than required at this level.

Amplitude Modulation   Applet 1   Applet 2   Applet 3   Applet 3

Frequency Modulation    Applet 1    Applet 2
