What is a full subtractor?

A half-subtractor lets you borrow out, but not borrow in. A full subtractor is made by combining two half-subtractor and adding an OR-gate. (lets you both BOR_in as well)


Half-Subtractor circuit using NOR gates?

By using 5 NOR gates, we can implements half-subtractor. The inputs for 1st NOR gate are A and B, for 2nd NOR gate inputs are the output of 1st NOR gate and A input, for 3rd NOR gate inputs are the output of 1st NOR gate and B input, for 4th NOR gate the inputs are gates 2 and 3, and for last gate input is the output of the 4th gate.
