8. Multiplexers and Demultiplexers - Part B
The chapter delves into multiplexers, encoders, decoders, and demultiplexers, explaining their functionalities and how to construct larger systems using these devices. It discusses the cascaded designs of multiplexers and encoders, and introduces priority encoders, detailing their advantages over conventional encoders. The theoretical details are supplemented with examples and applications, emphasizing practical implications and design methodologies in digital electronics.

What we have learnt
- Multiplexers can manage multiple input signals and route them through a single output line.
- Encoders convert input lines into a binary code, while priority encoders ensure that the highest priority input is processed first.
- Demultiplexers route input signals to one of several outputs based on select lines.
Key Concepts
- -- Multiplexer
- A multiplexer is a digital switch that allows multiple input signals to be directed to a single output line.
- -- Encoder
- An encoder converts multiple input signals into a coded output, representing the binary equivalent of the active input signal.
- -- Priority Encoder
- A priority encoder is a type of encoder where multiple active inputs are prioritized, and only the highest priority active input is encoded.
- -- Demultiplexer
- A demultiplexer takes a single input and channels it to one of several output lines based on select input signals.
- -- Decoder
- A decoder converts binary information from n input lines to 2^n distinct output lines.
