EC-4th sem Electronic Circuits List of Experiments (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..
