This operational clamping circuit was found in an American documentation from the 1980s. The source must be symmetrical, and the waveforms of the signals are given next to the diagram.
Any TTL inverter can be used in this circuit. We found it in documentation from the 80s, but it...
This circuit was found in a 1970 Philips documentation. The components are from the time, and...
In this circuit, obtained from a 1979 publication, IC1 is a 555 and IC2 is a 4020. The transistor is the...
