Digital Encoder

What is a binary encoder?

• A device that converts binary signals to decimal signals

• A device that converts decimal signals to binary signals

• A device that converts digital signals to analog signals

• A device that converts information from one format to another

Which of the following is the output of a binary encoder?

• Binary signal

• Decimal signal

• Analog signal

• All of the above

• 4

What is the purpose of a priority encoder?

• To convert binary numbers to decimal numbers

• To convert decimal numbers to binary numbers

• To convert gray code numbers to binary numbers

• To encode the highest-priority input in a set of inputs

Which input has the highest priority in a priority encoder?

• The first input

• The last input

• The input with the lowest value

• The input with the highest value

Which input has the highest priority in an 8-to-3 bit priority encoder?

• Input 0

What is a keyboard encoder?

• A device that converts analog signals to digital signals

• A device that converts digital signals to analog signals

• A device that encodes the keystrokes on a keyboard into digital signals

• A device that decodes digital signals into keystrokes on a keyboard

How does a keyboard encoder work?

• By scanning the keyboard matrix to determine which keys are pressed

• By measuring the voltage or current of each key

• By sending a signal to the computer for each keystroke

• By decoding the binary signals from the computer into keystrokes
