Get a slowish silicon diode such as a 1N400X and a high Q inductor in the
100uH to 1mH range.

Connect the two parts in series and attach them to a signal generator.

Connect a scope to the middle point of the series pair.

Tune the generator arount the point where the system resonates while
adjusting the amplitude and perhaps the offset.

You will see a spot where some very strange things happen.

"Strange things" are only strange to non-engineers ;-)

It's what you learn, after you know it all, that counts.
