Panels made in metal case with bench support and the electrical scheme on the front panel.The board shall allow the experimental study of AM modulation and demodulation techniques and the practising of the student with different circuit configurations of the most common modulators/demodulators. The panel shall group in its modules some of the circuits of the AM modulation and demodulation boards that can be most commonly met in practice, carried out in circuital configurations suitable to the educational use. The same panel shall contain a LF generator that can be used as generator of test modulating signals and a carrier generator. The panel shall be  supplied at +15 V, stabilized. The consumption must not exceed the 300 mA in the worst case.

Theoretical Recalls:

1. Amplitude Modulation  
2. Unrequired Modulation Products
3. Demodulation

Circuits of the Amplitude Modulations Panel:

1. AM elementary modulator
2. Collector modulator
3. Diode DSB modulator
4. Half wave and full wave modulator

Technical Features:
The board shall include a carrier frequency generator, variable in amplitude and frequency, and a testing tone generator, variable in amplitude. The working frequency of the circuits of the board shall be between 500 and 1500 kHz. Power supply: + 15 Vdc, 300 mA. With this module it must be possible to perform the following exercises: Study of the elementary modulator, Study of the collector modulator, Study of the diode DSB modulator, Study of the half wave modulator, Study of the full wave modulator.
