Input:

The sis_filtercascade_15242.xml stationxml file is an example of a filter cascade from SIS where the symmetry of the FIR filter was wrong, generating a response that is not correct. Note the large ripple in the passband. Choosing a channel from IRIS hopefully shows other more correct responses. You may also paste a URL to a stationxml, IRIS stationxml-resp from the NRL, or SIS extended stationxml file into the box to plot it.

Response Stage plot

Caveats:

Not all responses types are plotted currently, including:

• Gain-only Stages
• Polynomial
• Coefficients that are not DIGITAL
• Coefficients that have length zero numerator and denominator coefficients
• Coefficients that have denominator coefficients
• FIR that have length zero numerator coefficients
• PolesZeros that are not LAPLACE (RADIANS/SECOND)
• ResponseList
