These are frequently used in communication system such as telecommunication, networking, etc.. Similarly, in the digital domain, for easy transmission of data, it is often encrypted or placed within codes, and then transmitted.
Basically, Decoder is a combinational logic circuit that converts coded input to coded outputs provided both of these are different from one another. The name decoder means translating of coded information from one format into another. So the input code generally has fewer bits than output code word. A digital decoder converts a set of digital signals into corresponding decimal code. A decoder is also a most commonly used circuit in prior to the use of encoder. The encoded data is decoded for user interface in most of the output devices like monitors, calculator displays, printers, etc.
Before going into realities about Encoders and Decoders , let us have a concise thought regarding Multiplexing. Regularly we go over applications where it is expected to nourish a few input signals to a solitary load, each at once. This procedure of choosing one of the input signals to be fed to the load is known as Multiplexing. The invert of this operation, i. Similarly in a digital domain, for simplicity of transmission of information, the information is regularly scrambled or set inside codes and afterward, this secured code is transmitted. At the collector, the coded information is decoded or accumulated from the code and is handled to be shown or given to the load likewise.
Combinational logic is the concept in which two or more input state define one or more output state. Encoder and Decoder are the combinational logic circuits. In which we implement combinational logic with the help of boolean algebra. To encode something is to convert an unambiguous piece of information into a form of code that is not so clearly understood and the device which performs this operation is termed ad Encoder. Encoder : An Encoder is a device that converts the active data signal into a coded message format or it is a device that coverts analogue signal to digital signals. It is a combinational circuit, that converts binary information in the form of a 2N input lines into N output lines which represent N bit code for the input. When an input signal is applied to an encoder then logic circuitry involved within it converts that particular input into coded binary output.
Applications of the Encoder and Decoder. Speed synchronization of multiple motors in industries. War field flying robot with a night vision flying camera. Robotic vehicle with the metal detector. RF based home automation system. Automatic health monitoring systems.
Encoders translate rotary or linear motion into a digital signal. That signal is sent to a controller, which monitors motion parameters such as speed, rate, direction, distance, or position. Since , millions of EPC encoders have been applied for countless feedback requirements in nearly every industry. When selecting the right encoder for your application, it's vital to understand the role of the encoder in your motion control system. Encoders provide high-precision motion feedback while operating in extreme environmental conditions.
Prerequisite — Encoder , Decoders. Binary code of N digits can be used to store 2 N distinct elements of coded information. This is what encoders and decoders are used for. Encoders convert 2 N lines of input into a code of N bits and Decoders decode the N bits into 2 N lines.
In digital electronic projects, the encoder and decoder play an important role. It is used to convert the data from one form to another form. Generally, these are frequently used in the communication systems like telecommunication, networking, and transfer the data from one end to the other end. In the same way it is also used in the digital domain for easy transmission of data, placed with the codes and then transmitted. At the end of the receiver, the coded data are collected from the code and then processed to display.
