Functions

load_sample_signal(frequency=5.0, sampling_rate=100, duration=1.0)

Generate a sample sine-wave signal.

Parameters:

Name	Type	Description	Default
frequency	float	Frequency of the signal in Hz.	5.0
sampling_rate	int	Sampling rate in Hz.	100
duration	float	Duration of the signal in seconds.	1.0

Returns:

Type	Description
NDArrayReal	Signal data as a NumPy array.
