1.	A truth table with output columns numbered 0–15 may be for which type of decoder IC?(a) Hexadecimal 1-of-16(b) Dual octal outputs(c) Binary-to-hexadecimal(d) Hexadecimal-to-binaryI got this question during an interview for a job.The doubt is from Parity Generators/Checkers topic in section Combinational Circuits of Digital Circuits
Answer» Right answer is (a) Hexadecimal 1-of-16 Easy explanation: A binary decoder is a combinational logic circuit that decodes binary information from n-inputs to a MAXIMUM of 2^n outputs. A TRUTH table with output COLUMNS numbered 0–15 may be for Hexadecimal 1-of-16. Because hexadecimal OCCUPIES less space in a SYSTEM.
