Encoder Circuit. An encoder is a combinational circuit that performs the reverse operation of decoder. In a way it extracts information from packaged data.
Binary encoder circuit encoders as the name suggest encodes a larger bit of information into a smaller bit value. An encoder or simple encoder in digital electronics is a one hot to binary converter that is if there are 2 n input lines and at most only one of them will ever be high the binary code of this hot line is produced on the n bit output lines a binary encoder is the dual of a binary decoder. A decoder is a combination circuit meaning that it consists of various gates that put together a number of conditions carried by the input code.
For example a 4 to 2 simple encoder takes 4 input bits and produces 2 output bits.
An encoder is a circuit that changes a set of signals into a code. A mechanical absolute encoder is a common low cost option that is constructed with a metal disc and works as follow. An encoder is a circuit that changes a set of signals into a code. In a way it extracts information from packaged data.
