The figure shows how to use an 8080 in a digital to analog converter. The circuit is from a Radio Electronics from February 1978. The other components are from that time, except for the TTL.
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...
