Digital  Electronics 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..
1. To test and study of operation of all logic Gates for various IC's.
2. Implementation of AND, OR, NOT, NOR, EX-OR and X-Nor Gates by NAND and NOR Universal gates.
3. Binary Addition by Half Adder and Full Adder circuit.
4. Binary Subtraction by Half Subtractor and Full Subtractor circuit.
5. Design a BCD to excess-3 code converter.
6. Verification of the Demorgan's Theorem.
7. Study of RS, JK, T & D flip-flops. 
8. Multiplexer/Demultiplexer based boolean function realization.
9. Study and Application of 555 timer (Astable, Monostable, Schmitt trigger, VCO).
