Definition
- A decoder is a digital logic circuit that performs the reverse function of an encoder by taking binary input and activating one of several output lines based on the binary input code.
Characteristic Features
- The most common type of decoder is the binary-to-decimal decoder, which decodes a binary input into one of several possible decimal outputs.
Structure and Working Principle
- Decoders are commonly used in digital systems to select specific devices or functions based on binary input.
- It decodes the binary input into a one-hot representation, where exactly one output line is active (high) at a time based on the binary input.
Use/Application
- Decoders are used in various applications, including memory addressing, data demultiplexing, and control signal generation.
