This unique device provides a demonstration of frequency and amplitude modulation in radio communications. The unit generates a 10kHz carrier wave and accepts a modulation input from any signal generator source which would be typically in the 500Hz region. A simple switch applies the input to the carrier wave as either FM or AM modulation and the signal may be viewed on any oscilloscope. A miniature microphone is included so that speech modulation of the carrier can be seen. A 12V plug-top power unit is supplied together with full instructions.
