This is the circuit of an automotive voltage regulator from the 1970s. The circuit is entirely electromechanical based on the closing of a relay contacts according to the voltage.
We found this circuit in a 2004 documentation. The circuit consists of a standard lamp for testing...
In the figure we have the way to implement an oscillator from 100 kHz to 5 MHz with operational, being...
To obtain triangular signals, we have the circuit in the figure that uses two amplifiers. One of...
