This old circuit from the 80's generates logic signals with 50% active cycle (squares). The integrated circuit used is not common today, but equivalent logic functions can be used in a modern version.
This configuration enables the use of low current switches or sensors to control high power loads...
We found this circuit in an old amateur radio manual. The circuit makes use of PIN diodes to...
The purpose of this circuit is to invert the phase of a noise and apply it to the environment in...
