Study Notes
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
