Design Of Digital Circuits Lab Manual 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. Derive your conclusion. 3.4 Testing the Solution: Observation table for example: INPUT OUTPUT A B C D Y Y’ 1 × × × 0 0 0 0 0 0 0 1 0 0 1 0 0 0 1 1 0 1 0 0 0 1 0 1 0 1 1 0 0 1 1 1 4 Conclusions We can conclude that to implement any function we can use multiplexer.

Design Of Digital Circuits Lab Manual EXPERIMENT -8 1 AIM: (A) To implement 4-bit comparator. (B) Using 4-bit comparator implements 8-bit comparator. 2 TOOLS/APPARATUS: IC 7486, IC 7432, IC 7408, IC 7400, Power supply, Connecting wires, Multimeter etc. 3 STANDARD PROCEDURES: 3.1 Analyzing the Problem: The comparison of two numbers is an operator that determines one number is greater than, less than (or) equal to the other number. A magnitude comparator is a combinational circuit that compares two numbers A and B and determines their relative magnitude. The outcome of the comparator is specified by three binary variables that indicate whether A>B, A=B (or) A
