Encoder-Decoder Circuits: Encoder Basics

Encoder-Decoder Circuits

Encoder Circuits

• An encoder circuit is a combinational circuit that converts binary information from a larger number of inputs to a smaller number of outputs.
• The output of an encoder circuit is a binary code that represents the input information.
• Encoder circuits are used to reduce the number of wires required to transmit data.

Types of Encoder Circuits

• Binary Encoder: converts binary information from 2^n inputs to n outputs.
• Octal Encoder: converts binary information from 8 inputs to 3 outputs.
• Hexadecimal Encoder: converts binary information from 16 inputs to 4 outputs.

Decoder Circuits

• A decoder circuit is a combinational circuit that converts binary information from a smaller number of inputs to a larger number of outputs.
• The output of a decoder circuit is the original binary information that was encoded.
• Decoder circuits are used to recover the original data from the encoded binary code.

Types of Decoder Circuits

• Binary Decoder: converts binary information from n inputs to 2^n outputs.
• Octal Decoder: converts binary information from 3 inputs to 8 outputs.
• Hexadecimal Decoder: converts binary information from 4 inputs to 16 outputs.

Applications of Encoder-Decoder Circuits

• Data compression and transmission
• Error detection and correction
• Digital communication systems
• Computer networks
• Cryptography
