A repetitive pulse with a 50% duty cycle is being applied to the input of an RC integrator. If one time constant is less than one-fifth the pulse width, the capacitor will be able to fully charge and discharge.
Answer: Option A
The output of an RL differentiator is taken from across the inductor.
The output voltage of an RC integrator will eventually equal the voltage of a single input pulse if the input pulse width is less than 5 time constants.
Answer: Option B
The output of a differentiator could be considered a spike when the input pulse width is much longer than 5 time constants.
The output of an RC differentiator is taken from across the capacitor.
