Tiếng Việt Passive filters consist of components such as inductors and capacitors. They absorb harmonics by providing a low-impedance path for specific harmonics.
Advantages
- Simple structure
- Low cost
- High reliability
Disadvantages
- Larger size
- Only effective for fixed-order harmonics
- May resonate with system impedance
