Topic: Network Theory
The given circuit represents a (T-network with series capacitors 2C and a shunt inductor L)
- A. Low pass filter
- B. High pass filter
- C. Band pass filter
- D. Band stop filter
Answer: B. High pass filter
Explanation: The series capacitors block low-frequency signals and pass high frequencies, while the shunt inductor provides a low-impedance path to ground for low frequencies. This configuration operates as a high pass filter.
