The main focus will be on the Encoders and Decoders in Digital Electronics here. But first, we will have to learn about Multiplexers and Demultiplexers. Multiplexers and Demultiplexers also work together as many communication systems are bidirectional. Multiplexer It follows the many-to-one rule. It is a combinational circuit that has at most 2 n data inputs where 'n' is the number of 'selection lines.' Out of these input lines, anyone is selected and routed to form the only output line. The input consists of analog or digital data. To handle analog signals, transistor switches and relays are used to build the multiplexer. To handle digital signals, logic gates are used to build the multiplexer. Some types of Multiplexers 2-to-1 Multiplexer(with 1 select line). 4-to-1 Multiplexer(with 2 select lines). 8-to-1 Multiplexer(with 3 select lines). 16-to-1 Multiplexer(with 4 select lines). Applications of Multiplexers It is used as a one-way rotary swi...
