List of experiment (Expandable):
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 S/W (TINA-V7/ PSPICE/ Labview/ CIRCUIT MAKER).
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 prepared on PCB machine.
