Subtractor circuits are rarely encountered in digital systems (for reasons that will be explained later), but they nevertheless provide an interesting design opportunity. Like adders, the simplest subtracting circuits perform subtraction bit-by-bit from the LSB to the MSB, and they are most easily designed using the bit-slice approach. The design process closely …
