This document discusses various combinational logic circuits including adders, subtractors, multiplexers, demultiplexers, encoders, decoders, and seven segment decoders. It provides examples of how these circuits can be used in applications like controlling water pumping and building alarm devices. The document contains diagrams and explanations of half adders, full adders, half subtractors, full subtractors, multiplexers, demultiplexers, and seven segment decoders. It also discusses how to represent combinational logic functions using logic gates, Boolean algebra, and truth tables.
