The given figure shows the pole zero pattern of a filter in the s-plane. The filter in question is a
- A. Band elimination filter
- B. Band pass filter
- C. Low pass filter
- D. High pass filter
Answer: B. Band pass filter
Explanation: The pole-zero plot shows poles clustered around a center frequency $\omega_0$ and $-\omega_0$ on the imaginary axis, with a zero at the origin. This configuration characterizes a band pass filter.
