QUESTIONDesign a circuit using NAND gates that detects the “after” condition for two 2-bit values. That is, given two 2-bit variables x and y, F(x,y) = 1 when the unsigned integer value of x is less than the unsigned integer value of y.a)Give a truth table for the output of the circuit, F.ANSWER: The truth table isxyF(x,y)X1X0Y1Y0000000001100101001110100001010011010111110000100101010010111110001101011100111101 | P a g e
