Binary Encoder Truth Table. Octal to binary encoder is nothing but 8 to 3 encoder. From this truth table the boolean expression for the encoder above with data inputs d 0 to d 7 and outputs q 0 q 1 q 2 is given as.
Logic 0 or a logic 1. Here the encoder has 8 inputs and 3 outputs again only one input should be high 1 at any given time. The truth table for a 8 to 3 bit priority encoder is given as.
In the same way when d 3 1 and the other inputs are 0 the output produced is ba 11.
Y 1 i 2 i 3 i 6. Logical expression for a3 a2 a1 and a0.

It is to be observed from the table is the output yo is 1 when either input w1 or w3 is 1 also the output y1 is set to 1 when either input w2 or w3 is 1.
