Suggested by an American publication of 1964 this circuit is intended for the capture of signals from film tracks recorded by optical systems, common at the time.
This circuit was found in the SGS manual of linear integrated circuits of 1982. The CMRR depends on...
In the figure we have a receiver for frequency modulated light signals (see the transmitter in...
In the figure we have a high stability voltage reference, providing a voltage of 10 V at the...
