This 50% active cycle TTL clock generates signals from 4 to 20 Hz. Its power must be supplied with 5 V and other frequencies can be generated with capacitor replacement.
The frequency of this circuit depends on the capacitor. The unijunction transistor can be the...
We found this configuration with a logic circuit that is now uncommon in an 80's documentation. The circuit...
The purpose of this circuit found in a 1990s Popular Electronics is to increase the current...
