Perform signal analysis
[![Build Status][travis image]][travis link] [![PyPi Version][pypi ver image]][pypi ver link] [![Coverage Status][coveralls image]][coveralls link]
Python (2.7+/3.4+) routines for analyzing signals. Some of the functions include:
- Calculating Short-Term Fourier Transform
- Smoothing a signal
- Plotting an STFT’s spectrogram
- Calculating the peak hold of an STFT in the freq domain
- Plotting the peak hold of an STFT
The above functions are handy when analyzing signals recorded in the time domain, such as using a TEAC LX-10 data recorder, and seeing the frequency spectrum. This is usefull for Electromagnetic Compatibiliity (EMC) analyses.
You can install [siganalysis] either via the Python Package Index (PyPI) or from source.
To install using pip:
`bash $ pip install siganalysis `
[siganalysis] requires the following Python packages:
[siganalysis] is developed using [Scott Chacon]’s [GitHub Flow]. To contribute, fork [siganalysis], create a feature branch, and then submit a pull request. [GitHub Flow] is summarized as:
- Anything in the master branch is deployable
- To work on something new, create a descriptively named branch off of master (e.g., new-oauth2-scopes)
- Commit to that branch locally and regularly push your work to the same named branch on the server
- When you need feedback or help, or you think the brnach is ready for merging, open a [pull request].
- After someone else has reviewed and signed off on the feature, you can merge it into master.
- Once it is merged and pushed to master, you can and should deploy immediately.
### Running the Tests
[siganalysis] has been tested against Python 2.7 and Python 3.4. While [siganalysis] may work with other versions of Python, it hasn’t been tested with anything else at this time. Assuming you have [virtualenv] and [virtualenvwrapper] installed, you can run the following commands to clone the GitHub repository, create a virtualenv, and run the unit tests:
`bash $ git clone https://github.com/questrail/siganalysis.git $ cd siganalysis $ mkvirtualenv siganalysis $ pip install -r requirements.txt $ nosetests `
[siganalysis] is released under the MIT license. Please see the [LICENSE.txt] file for more information.
