Encoders Quiz

What is a binary encoder?

• A digital circuit that converts an input signal into a binary output code.

• A tool for encrypting data into a non-binary format

• A device that converts binary code into a digital signal

• A type of computer software used for encoding files

How many input lines does a 4-to-2 binary encoder have?

• 8

• 6

• 2

• 4

What is the purpose of a priority encoder?

• To convert decimal numbers into binary numbers

• To convert single input line into multiple output lines

• To convert binary data into analog signal

• To convert multiple input lines into a single output line based on the highest priority input.

How does a priority encoder determine the highest-priority input?

• By selecting the input with the lowest priority.

• By scanning the inputs from highest to lowest priority and selecting the first active (high) input encountered.

• By randomly selecting an input without considering priority.

• By scanning the inputs from lowest to highest priority and selecting the first active (high) input encountered.
