Welcome to discussion on
“ENCODER & MULTIPLEXER”
2. WHAT IS ENCODER ?
The encoder is a combinational circuit that performs the reverse
operation of the decoder. The encoder has a maximum of input 2 𝑛
and outputs n.
The simplest encoder is a 2 𝑛
-to-n binary encoder
One of 2 𝑛 inputs = 1
Output is an n-bit binary number

6. WHAT IS MULTIPLEXER?
Multiplexer means many into one. A multiplexer is a circuit
used to select and route any one of the several input signals
to a signal output.
8. Applications of Multiplexer
Multiplexer are used in various fields where
multiple data need to be transmitted using a single
line. Following are some of the applications of
multiplexers
1. Communication system
2. Telephone network
3. Computer memory
4. Transmission from the computer system of a
satellite
