Hi,

If I want to implement a 1-bit subtractor using XOR, NAND and not gates, how would I go about doing that? I am guessing it is a simple modification of the 1-bit adder but with the addition of NOT gates? I am not exactly sure where to place the NOT gates and was not able to find a diagram on the web. Any help would be great appreciated!

Thank you
