Asymmetric Baxter- King Filter
2010
Ginters Bušs

This paper proposes an extension of the Baxter-King symmetric band pass filter to an asymmetric case. It turns out the optimal correction scheme of the ideal filter weights is the same as in the symmetric version – cut the ideal filter at the appropriate length and add a constant to all filter weights to ensure zero weight on zero frequency. Since the symmetric Baxter-King filter is unable to extract the band of frequencies at the ends of the series, the extension to an asymmetric filter is useful whenever the real time estimation is needed. The developed filter can be used in any field of science where it is necessary to extract a band of frequencies from a signal.
