4. Definition of Encoder 1/5/2022 4 An encoder (or "simple encoder") in digital electronics is  a one-hot to binary converter. An encoder in digital electronics 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.

5. Working of Encoder 1/5/2022 5 An Encoder is a combinational circuit that  performs the reverse operation of Decoder . It has maximum of 2^n input lines and 'n' output lines, hence it encodes the information from 2^n inputs into an n-bit code. It will produce a binary code equivalent to the input, which is active High.

7. Definition of Decoder 1/5/2022 7 The decoder is an electronic device that is used to convert a digital signal to an analog signal. It allows a 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 decoders.

8. Working of Decoder 1/5/2022 8 A decoder is a multiple-input, multiple-output combinational logic circuit. It  converts the n bit data inputs into the coded 2 n  outputs . It decodes the information hidden by the encoder. While decoding, the decoder generally places a logic 1 at one of its outputs to create the exact code
