Description
Description
This project is meant to show students the process of amplitude modulation by using a diode or a transistor each fed with three series-connected voltage generators of the correct magnitude and frequency. This can be done as the sate of the diode and transistor supplied with low voltages are not in a zero input impedance state.
The three voltages represent, Bias voltage + carrier + information modulating signal
