This circuit was found in a 90’s Electronic Engineering. The integrated circuits are of the time and the diodes are of general use. The generated signal is sinusoidal.
This circuit monitors extra-low frequency (ELF) fields. We found it in an American documentation from the...
We can use any type of resistive transducer with central resistance in the range of 10 k ohms to 1...
This circuit controls two lamps so that when one increases in brightness the other decreases. The...
