Abstract Part1- I will build and observe the functioning of a 2-bit magnitude comparator using basic logic gates and the functioning of an 8-bit magnitude comparator using IC 7485. Part 2- I will build and observe the functioning of a multiplexer and demultiplexer and also the functioning of an encoder and decoder. I ntroduction Using Miltisim, I will construct and observe the way comparators, multiplexers, and demultiplexers function. I will observe how these components act much like analog logic gates. I will test the validity of given measurements. 3

Part 1: Methods and Procedures I. Parts List : 2-bit magnitude comparator:  5 - AND gates  2 – OR gates  2 – XOR gates  6 – NOT gates  1 – 1 KOhm resistor  4 – SPDT switches  3 – Digital probes  1 - VCC (5V)  1 - GND 8-bit magnitude comparator:  2 – 7485 ICs  1 – 1 KOhm resistor  16 – SPDT switches  3 – Digital probes  1 - VCC (5V)  1 - GND Part 1: Results and Figures Take screenshots of each circuit in part 1 after the circuit simulation. Be sure to include the multimeters in the screenshots. All screenshots of Multisim circuits must contain the date and time from the system tray. This section should include all raw data collected, e.g., voltage and current readings. All results are to be presented in both tabular and graphical form . All tables must have titles and all figures must have brief captions. Part 2: Methods and Procedures (This instruction box is to be deleted before submission of Lab report) List and describe the steps for the practical lab. A schematic of the experimental setup is also required. This section is the most important section of the report. Data representations and analysis are crucial in the engineering field. This section should include all raw data collected, e.g., voltage and current readings. All results are to be presented in both tabular and graphical form. All tables must have titles and all figures must have brief captions. 4

Part 2: Results and Figures Take screenshots of each circuit in part 1 after the circuit simulation. Be sure to include the multimeters in the screenshots. All screenshots of Multisim circuits must contain the date and time from the system tray. This section should include all raw data collected, e.g., voltage and current readings. All results are to be presented in both tabular and graphical form . All tables must have titles and all figures must have brief captions. Conclusion (This instruction box is to be deleted before submission of Lab report) What is a Conclusion? Write the Abstract, Introduction and Conclusion last! This section should reflect your understanding of the experiment conducted. Important points to include are a brief discussion of your results, an interpretation of the actual experimental results as they apply to the objectives of the experiment set out in the introduction should be given. Also, discuss any problems encountered and how they were resolved. (Students need to write this). 5
