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.
