General exam question G7C13
Subelement G7, PRACTICAL CIRCUITS· Group G7C
What term specifies a filter’s maximum ability to reject signals outside its passband?
- A.Notch depth
- B.Rolloff
- C.Insertion loss
- D.Ultimate rejection (correct answer)
WhyUltimate rejection is the term for a filter's maximum ability to reject signals outside its passband. A filter's ultimate rejection specifies the maximum amount of attenuation it can provide to signals well outside its passband, the deepest stop-band rejection the filter design achieves, answer D. Notch depth applies specifically to a notch filter's single rejection point, rolloff describes the transition slope rather than the maximum rejection level, and insertion loss describes passband attenuation, the opposite end of the filter's behavior, so A, B, and C are wrong.
