python-adc-eval |Lint| |PyPi Version| |Codestyle|
===================================================
A python-based ADC evaluation tool, suitable for standalone or library-based usage
Details
--------
Package based on
`esynr3z/adc-eval <https://github.com/esynr3z/adc-eval>`__
Tiny tools collection (Python
`NumPy <https://numpy.org/>`__\ +\ `Matplotlib <https://matplotlib.org/>`__
based) to do spectral analysis and calculate the key performance
parameters of an ADC. Just collect some data from the ADC, specify basic
ADC parameters and run analysis. See `example.ipynb <example.ipynb>`__
(you will need `Jupyter Notebook <https://jupyter.org/>`__ to be
installed).

tool.
USAGE
=======
To load the library in a module:
.. code-block:: python
import adc_eval
Given an array of values representing the output of an ADC, the spectrum can be analyzed with the following:
.. code-block:: python
import adc_eval
adc_eval.spectrum.analyze(<adc list>, <adc_bits>, <adc vref>, <adc fsamp>, window='hanning', no_plot=<True/False>)
