If two inputs are active on a priority encoder, which will be coded on the output?(a) The higher value(b) The lower value(c) Neither of the inputs(d) Both of the inputsI had been asked this question during an online exam.The origin of the question is Encoders topic in chapter Combinational Circuits of Digital Circuits

Answer»

Right answer is (a) The higher value

To explain: An ENCODER is a combinational CIRCUIT encoding the information of 2^N input LINES to n output lines, THUS producing the binary equivalent of the input. If two inputs are active on a priority encoder, the input of higher value will be coded in the output.
