FiltWNoiseGenerator¶

class acoular.signals.FiltWNoiseGenerator¶

Bases: WNoiseGenerator

Filtered white noise signal following an autoregressive (AR), moving-average (MA) or autoregressive moving-average (ARMA) process.

The desired frequency response of the filter can be defined by specifying the filter coefficients ar and ma. The RMS value specified via the rms attribute belongs to the white noise signal and differs from the RMS value of the filtered signal. For numerical stability at high orders, the filter is a combination of second order sections (sos).

signal()¶

Deliver the signal.

Returns:

Array of floats

The resulting signal as an array of length numsamples.
