In this lab, truth tables of various logic gates, flip flops are verified. Also working of various digital circuits like Multiplexers, Encoders, decoders, counters, shift registers are verified. Logic gates digital IC families (DTL, TTL, ECL, MOS, and CMOS), combinational circuits: arithmetic circuits, code converters, multiplexers and decoders; Sequential circuits: latches and flip-flops, counters and shift-registers. Sample and hold circuits, ADCs, DACs and semiconductor memories are studied.
