Wave Sources (pysit.core.wave_source)

Note

This section of the documentation is under construction. The source, however, is documented and you can access that via the Reference/API section.

Introduction

A PySIT wave_source is the implementation of the source profile function.

Getting Started

• Importing and invoking wave sources, RickerWavelet in particular

Using wave_source

• time and phase shifts

Function or Function-like Objects

• __call__ method

Gaussian Derivative Wavelets

• General specification in time and frequency domains
• Thresholds and peak frequencies

The Ricker Wavelet

• A special case of a Gaussian Derivative

The Gaussian Wavelet

• A special case of a Gaussian Derivative

Noise Sources

• Specification of distribution
• Warning: time and frequency domain are incoherent

Extending wave_source

• Expected input/output behavior
• Define if time or frequency domain
• Define _evaluate_time and _evaluate_frequency methods
• Array and scalar input
