4. Electronic fundamentals

In a diode clamper, if the resistor is removed making the time constant equal to C x r where r is the reverse resistance of the diode, this will ensure a

  • long time constant.
  • short time constant.
  • variable time constant.

Explanation from PART66Online

Removing the resistor leaves the diode's reverse resistance r in series with capacitor C. Because a reverse-biased diode has a very high resistance, the product C x r is large, giving a long time constant. This lets the capacitor hold its charge so the clamper maintains the DC level over the waveform.
