functionwavXFreqBSpline
Complex Frequency B-Spline wavelet
Information
This function generates the complex Frequency B-Spline wavelet function. It has no scaling function. Since this wavelet has theoretically unlimited support, the function range has to be defined with [low, high].
Inputs
| Type | Name | Default | Description |
|---|---|---|---|
| Real | low | -20 | Lower boundary of the wavelet function |
| Real | high | 20 | Higher boundary of the wavelet function |
| Integer | order | 2 | Wavelet order, a natural number, 1, 2, ... |
| Integer | points | 32 | Number of data points of the returned functions |
| Real | fb | 1 | Band width |
| Real | fc | 1 | Center frequency, a real number, e.g. 0.1, 0.5, 1, 1.5, ... |
