![]() The circuit diagram of 4 to 2 encoder is shown in the following figure. We can implement the above two Boolean functions by using two input OR gates. Inputsįrom Truth table, we can write the Boolean functions for each output as The Truth table of 4 to 2 encoder is shown below. The block diagram of 4 to 2 Encoder is shown in the following figure.Īt any time, only one of these 4 inputs can be ‘1’ in order to get the respective binary code at the output. Let 4 to 2 Encoder has four inputs Y 3, Y 2, Y 1 & Y 0 and two outputs A 1 & A 0. It is optional to represent the enable signal in encoders. ![]() Therefore, the encoder encodes 2 n input lines with ‘n’ bits. It will produce a binary code equivalent to the input, which is active High. It has maximum of 2 n input lines and ‘n’ output lines. An Encoder is a combinational circuit that performs the reverse operation of Decoder.
