What is Digital Encoder and How It Works

 Unlike a multiplexer that chooses one single data input line and then transmits that data to a single output line or switch, Digital Encoder more generally called a Binary Encoder takes all its data information one at a time and then turns them into a single encoded output. So we can say that a binary encoder, is a multi-input combinational logic circuit that transforms the logic level “1” data at its inputs into an equivalent binary code at its output.

A Digital Encoder is a combinational circuit that produces a special code at its outputs such as binary or BCD in acknowledgement of one or more active inputs. There are two main varieties of the digital encoder. The Binary Encoder and the Priority Encoder.

Binary Encoder turns one of the 2n inputs into an n-bit output. Then a binary encoder has fewer output bits than the input code. Binary encoders are beneficial for reducing data and can be formed from simple AND or OR gates. One of the main limitations of a standard binary encoder is that it would provide an error at its outputs if more than one input were active at the same time. To overcome this problem priority encoders were produced.

The Priority Encoder is another type of combinational circuit similar to a binary encoder, except that it produces an output code based on the highest prioritized input. Priority encoders are utilized extensively in digital and computer systems as microprocessor interrupt controllers where they identify the highest priority input.
