Detailed Description

Holds parameters defining a passband computed from snr.

This deconvolution operator has the option to determine the optimal shaping wavelet on the fly based on data bandwidth. This class is a struct in C++ disguise used to hold the encapsulation of the output of function(s) used to estimate the data bandwidth. This class is used only internally with CNR3CDecon to hold this information. It is not expected to be visible to python in MsPaSS, for example.

Member Function Documentation

bandwidth()

double mspass::algorithms::amplitudes::BandwidthData::bandwidth ( ) const

inline

Return bandwidth in dB.

                           {
    if (f_range <= 0.0)
      return 0.0;
    else {
      double ratio = high_edge_f / low_edge_f;
      return 20.0 * log10(ratio);
    }
  };

bandwidth_fraction()

double mspass::algorithms::amplitudes::BandwidthData::bandwidth_fraction ( ) const

inline

Return a metric of the estimated bandwidth divided by total frequency range

                                    {
    if (f_range <= 0.0)
      return 0.0;
    else
      return (high_edge_f - low_edge_f) / f_range;
  };
