README

        # ADC evaluation tool

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).
