A comparator circuit has two 2-bit inputs, A(0,1) and B(0,1) [4 total inputs], and three 1-bit outputs, G (A greater than B), E (equal), and L (A less than B) (hint: Compare two bits against two bits, for example, if inputs are 0010, then B is greater than A). Write the logic equation for each output, and draw the logic diagram for each output using 8 to 1 Multiplexers (3).

Verify that your design can be represented by the circuit below. 120 Full-Adder circuit Many of the logic gates you require may not exist in standard TTL/CMOS 74 series family of logic. For example in future designs you may require a 50 input OR gate. The 74 series does not have a 50 input OR gate.
