GenericSignalGenerator¶

class acoular.signals.GenericSignalGenerator¶

Bases: SignalGenerator

Generate signal from output of SamplesGenerator object.

This class can be used to inject arbitrary signals into Acoular processing chains. For example, it can be used to read signals from a HDF5 file or create any signal by using the acoular.sources.TimeSamples class.

source = Instance(SamplesGenerator)¶

Data source; SamplesGenerator or derived object.

amplitude = Float(1.0)¶

Amplitude of the signal. Defaults to 1.0.

sample_freq = Delegate('source')¶

Sampling frequency of output signal, as given by source.

num_samples = Property()¶

Number of samples to generate. Is set to source.num_samples by default.

loop_signal = Bool(True)¶

Boolean flag, if ‘True’ (default), signal track is repeated if requested num_samples is higher than available sample number

signal()¶

Deliver the signal.

Returns:

array of floats

The resulting signal as an array of length num_samples.
