About 4th Order Bandpass Filters
A 4th order bandpass filter provides steeper roll-off and better selectivity than 2nd order filters. It’s implemented as two cascaded 2nd order stages, each contributing to the overall frequency response.

Implementation Notes
This calculator provides component values for a cascaded 4th order bandpass filter. For best results, use components with tight tolerances (1% or better) and consider temperature coefficients for critical applications.
