Q.) How many OR gates are required for an octal-to- binary encoder?

(A) 3

(B) 2

(D) 10

Correct answer : Option (A) - 3

Explanation:

 an encoder is a combinational circuit encoding the information of 2n input lines to n output lines, thus producing the binary equivalent of the input. thus, in octal to binary encoder there are 8 (=23) inputs, thus 3 output lines.
