This debouncer circuit uses a transistor to produce a single pulse when the switch is triggered. The transistor conducts when the switch is opened. We found this configuration in an 80's publication.
The simple transistor test shown in the figure can be powered by a 9V battery. The test is for...
This small amplifier, close to 1 W, was found in a 1963 documentation. The class B circuit uses...
The circuit shown in the figure uses 2 of the 4 NAND gates of a 4011 and is designed to produce short...
