- Describe the function of a decoder circuit. identify the types and quantity of gates needed to implement a 3-to-8 decoder; either create (or give the location in the text) of a logic diagram of a decoder circuit A decoder is a circuit that changes a input code into a set of signals. It is just the reverse process of encoding, A common type of decoder is a binary decoder, which is a combinational logic circuit that converts binary information from the n coded inputs to a maximum of 2n unique outputs. It takes a binary input, usually in a coded form, and produces a one-bit output, on each of a number of output lines. The logic state (1 or 0) on any of the output lines depends on a particular code appearing on the input lines. Binary decoders are used in a wide variety of applications, including data demultiplexing, seven segment displays, and memory address decoding. If we want to buy a 1 of 8 decoder/ demultiplexer, please give the…Binary to Octal Decoder using 7-Segment Display. write the k-map and use 4 input and 7output?1.
