Quizplus · Accepted Answer

The tracking A/D converter, also known as a servo or tracking converter, can oscillate between two binary states when the analog input is constant. This is because the converter continually adjusts its output to match the input, and when the input value is at the boundary between two digital values, it can cause the output to switch back and forth between these values.
