RGTU/RGPV EX-403 Digital Electronics Logic Design I  List of Experiments (Expandable):

1. Verification of all the logic gates.
2. Design of BCD to Excess-3 code converter.
3. Implementation of NAND & NOR as Universal gate.
4. Design of RS, JK, T& D Flip flop.
5. Multiplexer /Demultipexer based boolean function
6. Design of combinational circuit for the
(iii) Half subtractor
(iv) Full subtractor
7. Design various A-D  & D-A convertors.

NOTE- - All experiments (wherever applicable) should be performed through the following steps.
Step 1: Circuit should be designed/ drafted on paper.
Step 2: Where ever applicable the designed/drafted
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.
Step 4: Where ever required the bread board circuit should be fabricated on
PCB.
