Found in documentation from the 1980s, this circuit uses an operational amplifier from that time. Transistors are also from the era, and general-purpose equivalents can now be used.
Two potentiometers mounted at right angles, so that they can be operated by a lever, form a very...
The purpose of this modified astable is to make the initial pulses have the same duration as the...
This circuit was found in an American 80's circuit board. The components used are current except the...
