To understand how the output voltage is shaped by a differentiator, you must consider the response to the falling pulse edge the response to the rising pulse edge the response between the rising and falling edges All 2. A steady-state condition is reached when the output voltage reaches the input voltage the output voltage reaches the effective value of the input voltage the output voltage reaches the average value of the input voltage the output voltage reaches approximately 63% of the input voltage 3. Which of the following is true for a capacitor? A capacitor’s voltage cannot change instantaneously A capacitor acts like a short to instantaneous changes in current A capacitor acts like an open to dc All 4. If the capacitor in an RC integrator shorts, the output would measure the same as the input would measure zero volts is at ground None of the above 5. In electronic systems, repetitive-pulse waveforms are encountered twice as often as single pulses less often than single pulses about as often as single pulses more often than single pulses 6. In an RC differentiator, the capacitor charges exponentially at a rate depending on the input voltage charges when the input voltage is decreasing charges exponentially at a rate depending on the RC time constant charges to approximately one time constant 7. What is a circuit that produces short-duration spikes? An RL integrator A pulse waveform-to-dc converter A timing circuit A trigger pulse generator 8. With an RL integrator, at the instant of the rising pulse edge, 63 percent of the input voltage is across the resistor all the input voltage is across the inductor all the input voltage is across the resistor 63 percent of the input voltage is across the inductor 9. An RL integrator and an RC differentiator can act as what types of filters, respectively? low-pass, high-pass low-pass, low-pass high-pass, low-pass high-pass, high-pass 10. An RC differentiator acts as a band-pass filter high-pass filter band-stop filter low-pass filter Loading … Question 1 of 10
