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.
Found in Ferranti's 1968 documentation, this circuit uses a Darlington photo transistor to drive a...
Found in documentation from the 70s, this circuit uses components from that time. Some of these...
This circuit monitors the state of a 12 V battery and can be used directly with one, or even in a...
