BCD Decoder Schematic

The other posts show the bits and logic schematics for relay implementation of typical gate level logic. This is the main schematic of the BCD decoder. It does have a bug in that the circuit that controls all of the output relays (EN’) will not work. Due to not thinking about other relay’s giving the […]
