A pulse- Waveform to DC convertor makes use of an integrator:
A) with a time constant shorter than the width of the input pulse.
B) with a time constant much wider than the width of the input pulse.
C) with an extremely large time constant.
D) either B or C

Question

Quizplus · Accepted Answer

A pulse-waveform to DC converter, when using an integrator, requires the integrator to have a time constant significantly longer than the width of the input pulse. This ensures that the integrator averages the pulses over time, effectively converting the varying pulse waveform into a steady DC level. Both options B and C describe scenarios where the time constant of the integrator is longer than the pulse width, which is necessary for effective conversion.
