In a certain low-pass filter, fc = 3.5 kHz. Its pass-band is_______________?
Correct answer: A. 0 Hz to 3.5 kHz
- A. 0 Hz to 3.5 kHz
- B. 0 Hz
- C. 3.5 kHz
- D. 7 kHz
Explanation
A low-pass filter passes frequencies from DC, or 0 Hz, up to its cutoff frequency. With f_c = 3.5 kHz, the pass-band is 0 to 3.5 kHz.
