In the figure below we have the typical circuit of an automotive star alternator with the rectifier sector. The diodes depend on the current and the circuit is given as a reference for a Ford vehicle.
This circuit is from the 1974 Motorola Unijunction Trigger Circuits for Gated Thyristor. The triac...
Found in old American documentation, this circuit can divide the frequency of a signal by 2 or 3...
This transceiver is also low power, but this time, it can generate signals in the 144 MHz band. In the...
