This course covers Boolean algebra, operation of digital combinational gates, flip-flop circuitry, shift registers and clock circuits and design combinational and sequential circuits. The laboratory is an essential phase of this course, which emphasizes the use of logic probes, logic pulsers and logic clips on gating circuits, flip-flops, counters, shift registers and multiplexers and demultiplexers.
