psd#
- property ToneToNoiseRatio.psd: Field#
Input power spectral density (PSD).
The PSD field has the following characteristics:
num_entities
= 1location
= “TimeFreq_sets”data
: Vector of amplitude values in unit^2/Hztime_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.
