With this passive circuit it is possible to modulated in amplitude a low intensity RF signal. The circuit is from old American documentation and uses a germanium diode as its main component.
This circuit is from the Motorola Linear Databook published in 1990. The circuit for 1 kHz can be...
We find this circuit in an earlier American publication of 1978. The components are no longer...
This simple circuit that interrupts the supply of a 12 V load in the event of an overvoltage was found in...
