The Performance Analysis of Second Order Band-pass Filter

The design of Band-pass filter is an important component in electronic circuits. The center frequency, bandwidth and phase-shift are most concerned parameters in design. We analyze the transfer function performance of second-order passive band-pass filter in this paper. The constraint conditions between center frequency, bandwidth and phase-shift are derived. In consideration of the fact that active filter is consisted by passive filters and active components. The derived constraint conditions are the same with active band-pass filters.
