List of Experiments:
All experiments (wherever applicable) should be performed through the following steps.
Step 1: Circuit should be designed/drafted on paper.
Step 2: The designed/drafted circuit should be simulated using Simulation Software
Step 3: The designed/drafted circuit should be tested on the bread board and compare the results with
the simulated results.
Step 4: The bread board circuit should be fabricated on PCB by one batch using PCB machine.
1. Study of CRO and Function Generator.
2. Displacement measurement by LVDT.
3. Force measurement by strain gauge.
4. Measurement of Capacitor, Self-induction using Q-meter.
