Encoders and Decoders : Types and Its Applications The encoders and decoders are designed with logic gates such as AND gate. There are different types of decoders like 4, 8, and 16 decoders and the truth table of decoder depends upon a particular decoder chosen by the user. The subsequent description is about a 4 bit decoder and its truth table. Construct 2 to 4 decoder with truth table and logic diagram Step 1. Now we know possible outputs for 2 inputs, so construct 2 to 4 decoder , having 2 input lines, a enable input and 4 output lines. In the below diagram, given input represented as I 1 and I 0 , all possible outputs named as O 0, O 1, O 2, & O 3 and a E were represented by Enable input. Digital Circuits Encoders Tutorialspoint The circuit diagram of 4 to 2 priority encoder is shown in the following figure. The above circuit diagram contains two 2 input OR gates, one 4 input OR gate, one 2input AND gate & an inverter. Here AND gate & inverter combination are used for producing a valid code at the outputs, even when multiple inputs are equal to ‘1’ at the same time. Designing of 3 to 8 Line Decoder and Demultiplexer Using ... The circuit shows the 1 to 2 decoder logic. 1 to 2 Decoder Circuit A demultiplexer is a device that takes a single input and gives one of the several output lines. Binary Decoder used to Decode a Binary Codes Here a much larger 4 (3 data plus 1 enable) to 16 line binary decoder has been implemented using two smaller 3 to 8 decoders. A 4 to 16 Binary Decoder Configuration Inputs A, B, C are used to select which output on either decoder will be at logic “1” (HIGH) and input D is used with the enable input to select which encoder either the first ... Assignment # 2 (Solution) Assignment # 2 (Solution) Problem 1: Design a combinational circuit with three inputs, x, y and z, and the three outputs, A, B, and C. when the binary input is 0, 1, 2, or 3, the binary output is one greater than the input.
