1. multiplexer

2. Title of Experiment
Design and implement a binary full adder and full Subtractor using a dual 4-to-1 line multiplexer (74LS153) and a single Hex Inverter (7404).

3. What Information does following images convey???

4. Answer is
Out of for lanes only one lane is clear or GREEN at time.

5. Multiplexer
Multiplexer is combinational logic network which has 2n inputs, n select lines and has only one output.

12. Procedure
Use K-Map to find expressions for Sum and Carry and implement using Multiplexer.
Connections are made as per the circuit diagram, for Full Adder.
Give the input digital values as per the truth table and verify the output on the LEDs of the trainer kit.
Similarly use K-Map to find expressions for Difference and Borrow and repeat the steps 2 and 3 for Full Subtractor.
