PeriodicSignalGenerator

class acoular.signals.PeriodicSignalGenerator

Bases: SignalGenerator

Abstract base class for periodic signal generators.

The PeriodicSignalGenerator class defines the common interface for all SignalGenerator-derived classes with periodic signals. This class may be used as a base for class handling periodic signals that can be characterized by their frequency, phase and amplitude.

It should not be used directly as it contains no real functionality.

phase = Float(0.0, desc='Phase')

The phase of the signal (in radians). Default is 0.0.

amplitude = Float(1.0)

The amplitude of the signal. Default is 1.0.
