Definition of encoder and decoder??In briefly
Answers
Answer:
Encoders are combinational logic circuits and they are exactly opposite of decoders. They accept one or more inputs and generate a multibit output code. Encoders perform exactly reverse operation than decoder. ... If a device output code has fewer bits than the input code has, the device is usually called an encoder.

The encoders and decoders play an essential role in digital electronics .
- Encoders & decoders are used to convert data from one form to another form.
- These are frequently used in communication system such as tele-communication, networking, etc..to transfer data from one end to the other end.
- Similarly, in the digital domain, for easy transmission of data, it is often encrypted or placed within codes, and then transmitted. At the receiver, the coded data is decrypted or gathered from the code and is processed in order to be displayed or given to the load accordingly.
Types of Encoders and Decoders
An encoder is an electronic device used to convert an analogue signal to a digital signal such as a BCD code. It has a number of input lines, but only one of the inputs is activated at a given time and produces an N-bit output code that depends on the activated input. The encoders and decoders are used in many electronics projects to compress the multiple number of inputs into smaller number of outputs. The encoder allows 2 power N inputs and generates N-number of outputs. For example, in 4-2 encoder, if we give 4 inputs it produces only 2 outputs.

The decoder is an electronic device that is used to convert digital signal to an analogue signal. It allows single input line and produces multiple output lines. The decoders are used in many communication projects that are used to communicate between two devices. The decoder allows N- inputs and generates 2 power N-numbers of outputs. For example, if we give 2 inputs that will produce 4 outputs by using 4 by 2 decoder.
