Congratulations – you have completed Passive Filters Online Test Set 1.
You scored 2 points out of 8 points total.
Your answers are shown below:
1. A sinusoidal voltage with a peak-to-peak value of 18 V is applied to an RC low-pass filter. If the reactance at the input frequency is zero, the output voltage is
- 18 V peak-to-peak
- zero
- 9 V peak-to-peak
- 12.74 V peak-to-peak
2. The same signal in Problem 2 is applied to an RC high-pass filter. If the reactance is zero at the input frequency, the output voltage is
- 12.73 V peak-to-peak
- 18 V peak-to-peak
- 9 V peak-to-peak
- zero
3. The maximum output voltage of a certain low-pass filter is 15 V. The output voltage at the critical frequency is
- 10.60 V
- 0 V
- 21.21 V
- 15 V
4. In a certain low-pass filter, fc = 3.5 kHz.if the input voltage is a 6 V sine wave with a dc level of 10 V, what is the output voltage magnitude?
- 0 V
- 5.97 V
- 6 V
- 597 mV
5. In a series resonant band-pass filter, a lower value of Q results in
- a higher impedance
- a smaller bandwidth
- a higher resonant frequency
- a larger bandwidth
6. At a certain frequency, the output voltage of a filter is 6 V and the input is 12 V.the filter’s bandwidth is
- 530 Hz
- 106 Hz
- 11.5 Hz
- 53 Hz
7. In a certain parallel resonant band-pass filter, the resonant frequency is 14 kHz. If the bandwidth is 4 kHz, the lower frequency
- is 7 kHz
- is 10 kHz
- is 12 kHz
- cannot be determined
8. In a certain low-pass filter, fc = 3.5 kHz. Its passband is
- 3.5 kHz
- 0 Hz
- 0 Hz to 3.5 kHz
- 7 kHz
