signalyzer 0.3.0

Signal analyzer for time-discrete, equidistant measured signals

---

Signalyzer

signalyzer is a Python package to analyze and process time-discrete, equidistant measured signals, and visualize them with the open source Plotly library for Python.

Main features of the signalyzer package are

• transform and combine measured signals into a new one
• descriptive statistics over the measured signal
• interactive plotting of the measured signal with Plotly
• integrating (accumulating) of the measured signal
• differentiating of the measured signal
• clipping of the measured signal
• rate limiting of the measured signal
• filtering of the measured signal
• logical operations between measured signals
• prioritizing measured logic signals with a priority encoder
• smoothing of the measured signal with statistics
• process measured signals with a moving window
• moving sample value (event) counter
• moving averages with window statistics
• moving differentiation
• moving OLS linear regression with window statistics
• shifting (moving) of the measured signal
• slicing of the measured signal
• evaluate statemachine transitions observed by measured state signal

Important: The signalyzer package is best used within JupyterLab a web-based interactive development environment for Jupyter notebooks or with Plotly Dash, Streamlit or Jupyter voila to build standalone web applications and dashboards.

Development

Getting the Source

This project is hosted on gitlab. You can clone this project directly using this command:

> git clone https://gitlab.com/signalytics/signalyzer.git

Building a Distribution

To build a distribution of this project local, use this command:

> make build

The generated the distribution artifacts can be found in the ./dist folder of the cloned project on your machine.

Building the Documentation

Building the documentation requires Sphinx, the Furo theme, the Sphinx extensions sphinx-copybutton and sphinx-plotly-directive.

The required Python packages can be installed on your local machine using pip, use this commands:

> pip install sphinx
> pip install furo
> pip install sphinx-copybutton
> pip install sphinx-plotly-directive

To build the documentation of this project local, use this command:

> make docs

The generated HTML documentation artifact can be found in the ./docs/_build/html folder of the cloned project on your machine.
