This circuit was obtained from an 80's Radio Electronics. The circuit decodes “scrambled” or sinusoidal encoded signals by providing an audio signal at the output.
In applications where there is no danger of any contact with live points on the circuit by the...
This is an LED effect that we found in a 1988 documentation. The circuit drives LEDs with a...
