Combinational logic 2

This document discusses various combinational logic circuits including encoders, decoders, multiplexers, and parity generators. It provides details on 4-to-2 encoders and describes how they encode 4 input lines into 2 output lines. It also discusses priority encoders, octal-to-binary encoders, and multiplexers with examples of 4-to-1 and 8-to-1 multiplexer truth tables. The document concludes with explanations of exclusive OR gates, equivalence operations, and how to implement Boolean functions using multiplexers.
