The circuit shown in the figure can be designed with more modern operational amplifiers, as it is from 1994 documentation by National Semiconductor. The power supply must be symmetrical.
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...
