In the figure we have the way to implement a logic gate or (OR) with an LM393. The circuit must be powered by a symmetrical source and other operational ones can be used.
Using two of the 4 NAND gates of the integrated 4001, the circuit in the figure activates the...
This traditional 3-channel mixer configuration with FET appears elsewhere on this site. The FET...
This circuit was obtained in an old American manual. The circuit is valid for any operational. The...
