9.7 Multiplexers
A multiplexer, abbreviated mux, is a device that has multiple inputs and one output. The schematic symbol for...
9.6 Demultiplexers
A demultiplexer, sometimes abbreviated dmux, is a circuit that has one input and more than one output. It is used when...
9.5 Encoder
What is an Encoder? An encoder is a circuit that changes a set of signals into a code. Let’s begin making a 2-to-1...
9.4 Decoder
A decoder is a circuit that changes a code into a set of signals. It is called a decoder because it does the reverse of...
9.3 Full-Adder
The half-adder is extremely useful until you want to add more that one binary digit quantities. The slow way to develop...
9.2 Half-Adder
As a first example of useful combinational logic, let’s build a device that can add two binary digits together. We...
9.1 Introduction to Combinational Logic Functions
The term “combinational” comes to us from mathematics. In mathematics a combination is an unordered set, which is a...
