    Tips: Passive filter versus active filter
    Passive filter advantages are simple circuit, no need of DC power supply, and high reliability. It has its own disadvantages: signal inside pass band has energy consumption; load effect is obvious; it is easy to have electromagnetic induction when using electrical-induce element. When inductance(L) is large, filter dimension and weight is also large, not suitable in low frequency field.
    Active filter advantages: signal inside pass band has no energy consumption, and also can be amplified; load effect is not obvious, and mutual effect is very small for multilevel linkage. Taking cascading method is easy to constitute high-stage filter, which is in small dimension, light weight, no need of magnetic shielding (due to no use of inductance element). It also has some disadvantages. Since it is limited by band width of active component in the range of pass band, it needs to be energized by DC power supply. Thus reliability is not as good as passive filter. It is not suitable in high-voltage, high-frequency, large-power occasions.
