Found in a 1968 EEE, this circuit uses transistors from that time. The output is 300 ns. Transistors can be replaced with modern equivalents.
We found this circuit in an American documentation from the 60's. The transistors are made of...
The accuracy of this circuit depends on adjustments made with capacitors of small tolerances of known...
The figure shows how to implement an OR function with two inputs, using a relay. The relay...
