A digital voltmeter takes 20 ms to integrate and 30 ms for the rest of its cycle. Its maximum reading rate is

  • A.33 readings per second
  • B.10 readings per second
  • C.20 readings per second
  • D.50 readings per second

Answer: C

The whole cycle is fifty milliseconds, so twenty readings a second. An integrating instrument is necessarily slow for this reason, and a successive approximation converter of the same resolution would manage thousands of readings a second.
