Stringing up outdoor lights, had a thought ...
In the world of analog signal processing, the active ("ideal") rectifier opamp circuits (half-wave and full-wave) have been around since the 60's. Back then, the idea of running 1.6 MHz through one was somewhere between a pipe dream and a joke.
Fast-forward 50 years, and there are some pretty fast opamps available. Has anyone tried, or seen, a broadcast band AM demodulator with an opamp active rectifier as the detector?
