psd#

property ToneToNoiseRatio.psd: Field#

Input power spectral density (PSD).

The PSD field has the following characteristics:

  • num_entities = 1

  • location = “TimeFreq_sets”

  • data: Vector of amplitude values in unit^2/Hz

  • time_freq_support: Vector of regularly spaced frequencies in Hz associated with amplitude values (from 0 Hz to the maximum frequency)

  • unit = “<unit>^2/Hz” (where <unit> is Pa for example).

You can use the function create_scalar_field() to create the field.
