Resonant Circuit Demonstrator
by Dennis L Feucht
This simple project is essentially a three-stage amplifier with parallel-resonant circuits in each, to provide a tuned circuit with three frequency peaks in the 1 to 10 MHz range at the output. It was originally put together as a trade show demonstrator for sweeping function generators. The three different resonant circuits can also be used to study how multiple resonances combine to form an overall response.
