COMP122: Class Assignment 3

Following digital circuit is consisted of AND gate OR gate, NAND gate. NAND gate is AND gate that has a complement in the output shown by the circle. So, basically NAND of two inputs X  and Y is (XY)’ where (XY)’ denotes complement of (XY).     Problem statement:  Given the circuit and the table that provides the values for A, B, C and D fill the table below with values of X and Y.
