List of experiments
(1) Verify Truth Table of Logic Gates AND, OR, NAND, NOR, EX-OR, EX-NOR, NOT, and Buffer gates, and demonstrate the use of the universal NAND gate.
(2) Construct the logic circuit to simplify a Boolean function and verify De Morgan’s theorem for 2 variables.
(3) Realize half/full adder and half subtractor, and full subtractor circuits using logic gates.
(4) Realize a 4-bit parallel adder/Subtractors using IC 7483 and perform BCD to Excess-3 code conversion and Vice - Versa.
(5) Realize of Binary to Gray code conversion and Gray-to-Binary code conversion.
(6) Design, implement, and test Ring counter and Johnson counter circuits.
(7) Design and investigate the operation of 4-bit shift registers with parallel loading.
(8) Design, implement, and testing a Sequence generator.
(9) Realize 3-bit counters as a sequential circuit and design MOD – N counters using ICs 7476, 7490, 74192.
(10) Verify the logic operation of RS and JK flip-flops and obtain their truth tables.
