A dual slope converter charges its integrator for 100 ms and takes 40 ms to discharge with a 10 V reference. The input voltage was

  • A.0.4 V
  • B.4 V
  • C.25 V
  • D.10 V

Answer: B

The input is the reference multiplied by the ratio of discharge time to charge time, that is \( 10 \times 40/100 = 4 \) V. Neither the capacitance nor the clock frequency enters, which is the structural advantage of the method.
