Bases: obspy.core.inventory.response.ResponseStage

From the StationXML Definition:
Response: complex poles and zeros. Corresponds to SEED blockette 53.

The response stage is used for the analog stages of the filter system and the description of infinite impulse response (IIR) digital filters.

Has all the arguments of the parent class ResponseStage and the following:

Parameters:
  • pz_transfer_function_type (str)

    A string describing the type of transfer function. Can be one of:

    • LAPLACE (RADIANS/SECOND)
    • LAPLACE (HERTZ)
    • DIGITAL (Z-TRANSFORM)

    The function tries to match inputs to one of three types if it can.

  • normalization_frequency (float) The frequency at which the normalization factor is normalized.
  • zeros (list of complex) All zeros of the stage.
  • poles (list of complex) All poles of the stage.
  • normalization_factor (float, optional)
