Q20 / 100
What is an "encoder" circuit, and how does it relate to a decoder?
Correct! Well done.
Incorrect.
The correct answer is A) An encoder performs the opposite function of a decoder — it converts multiple input lines (typically one active at a time) into a smaller binary code representing which input was active
A
Correct Answer
An encoder performs the opposite function of a decoder — it converts multiple input lines (typically one active at a time) into a smaller binary code representing which input was active
Explanation
Encoders compress information from many input lines into a compact binary code (e.g., an 8-to-3 encoder converts one of 8 active inputs into a 3-bit code), the reverse operation of a decoder.
