18CSL37 Analog and Digital Electronics Laboratory syllabus for IS

Laboratory Programs:

PART A (Analog Electronic Circuits)

1. Design an astable multivibrator ciruit for three cases of duty cycle (50%, <50% and >50%) using NE 555 timer IC. Simulate the same for any one duty cycle.

2. Using ua 741 Opamp, design a 1 kHz Relaxation Oscillator with 50% duty cycle. And simulate the same.

3. Using ua 741 opamap, design a window comparate for any given UTP and LTP. And simulate the same.

PART B (Digital Electronic Circuits)

4. Design and implement Half adder, Full Adder, Half Subtractor, Full Subtractor using basic gates. And implement the same in HDL.

5. Given a 4-variable logic expression, simplify it using appropriate technique and realize the simplified logic expression using 8:1 multiplexer IC. And implement the same in HDL.

6. Realize a J-K Master / Slave Flip-Flop using NAND gates and verify its truth table. And implement the same in HDL.

7. Design and implement code converter I)Binary to Gray (II) Gray to Binary Code using basic gates.

8. Design and implement a mod-n (n<8) synchronous up counter using J-K Flip-Flop ICs and demonstrate its working.

9. Design and implement an asynchronous counter using decade counter IC to count up from 0 to n (n<=9) and demonstrate on 7-segment display (using IC-7447)

Laboratory Outcomes:

The student should be able to:

• Use appropriate design equations / methods to design the given circuit.

• Examine and verify the design of both analog and digital circuits using simulators.

• Make us of electronic components, ICs, instruments and tools for design and testing of circuits for the given the appropriate inputs.

• Compile a laboratory journal which includes; aim, tool/instruments/software/components used, design equations used and designs, schematics, program listing, procedure followed, relevant theory, results as graphs and tables, interpreting and concluding the findings.

Conduct of Practical Examination:

• Experiment distribution

• For laboratories having only one part: Students are allowed to pick one experiment from the lot with equal opportunity.
• For laboratories having PART A and PART B: Students are allowed to pick one experiment from PART A and one experiment from PART B, with equal opportunity.

• Change of experiment is allowed only once and marks allotted for procedure to be made zero of the changed part only.

• Marks Distribution (Courseed to change in accoradance with university regulations)

a) For laboratories having only one part – Procedure + Execution + Viva-Voce: 15+70+15 = 100 Marks

b) For laboratories having PART A and PART B

i. Part A – Procedure + Execution + Viva = 6 + 28 + 6 = 40 Marks

ii. Part B – Procedure + Execution + Viva = 9 + 42 + 9 = 60 Marks
