This protection circuit trips by quickly blowing the fuse in the event of an overcurrent. The circuit is from a 1964 Electgronic Design. The transistor can be general-purpose.
This RS flip-flop uses two type 4N26 optical couplers and is characterized by the very high...
This circuit produces a sine 1 kHz signal. The frequency is given by C1, C2 and C3. This is a...
This circuit is a documentation of the 70's and therefore valid for analog lines. What the circuit...
