Twin-T filter itself is called as Notch filter, they are band reject filters.

Rejection frequency is the range of frequency rejected by filter, it is on applicable if R1=R2 and C1=C2.

Given frequency response passes a definite band of frequency and surely it is a band pass filter.

An ideal filter shows ideal performance and change from pass band to reject band occurs abruptly.

Notch filter transfer function is a very complex one and contains higher order of three.

Tuned LCR circuit in series and parallel combination allows a specific band of frequency to pass through and is band pass filter.

Lead network, lag network are composed of resistance and capacitive components using different configurations.

Dynamic compensation is used for improving dynamic performance of the system, it is achieved by proper selection of resistance and use of amplifiers to reduce the effect of losses.

Bridge-T filters reject a specific band of frequency and allow other frequencies to pass through. Hence it is a band reject filter.

A low-pass filter means, which passes all frequencies less than cut-off frequency. That is pass band will be less than cut-off frequency.
