3.3 Implementing the Solution
Plug the chips you will be using into the breadboard. Point all the chips in the same direction with pin
1 at the upper-left corner. (Pin 1 is often identified by a dot or a notch next to it on the chip package).
Connect +5V and GND pins of each chip to the power and ground bus strips on the breadboard.
Make the connections as per the circuit diagram.
Switch on VCC and apply various combinations of input according to truth table.
Take 2 4bit nos & Write output in observation table.
For 8 bit Magnitude Comparator connect two 4 bit Magnitude Comparator as shown in diagram and
compare 8 bit nos.
