NOTE- - All experiments (wherever applicable) should be performed through the following steps.
circuit should be simulated using Simulation S/W (TINA-V7/ PSPICE/ Labview/ CIRCUIT MAKER etc.).
Step 3: The designed/drafted circuit should be tested on the bread board and compare the results with
the simulated results.
