Therefore, the logical expression for the 3 input would be: output = (input = 3) ? 011 : (other inputs) The logical expression for the encoder can be represented using a truth table, with each octal digit as one input and the corresponding 3-bit binary output.įor example, if the input is the octal digit 3, the binary output would be 011. Each octal digit (0-7) is mapped to a 3-bit binary number. Logic Diagram:Īn octal to binary encoder can be represented using a logical expression. As shown in the following figure, an octal-to-binary encoder takes 8 input lines and generates 3 output lines. For simple encoders, it is assumed that only one input line is active at a time.Īs an example, let’s consider Octal to Binary encoder. ![]() Encoders convert 2N lines of input into a code of N bits and Decoders decode the N bits into 2N lines.Įncoders – An encoder is a combinational circuit that converts binary information in the form of a 2N input lines into N output lines, which represent N bit code for the input. This is what encoders and decoders are used for.
