# F0 IIR Simulations

## Context

 Simulation made with VHD_Lib design Validation_IIR_f0_LFR **r643**.

 To reproduce, run **generate.xsh** script with the number of iterations you want as parameter

```bash

 ./generate.xsh 10

```

 Then to plot results open **plot_results** notebook.

## Notebook 

```python

import numpy as np

import matplotlib.pyplot as plt

import glob 

import pandas as pds

```

```python

for folder in glob.glob("./2016*"):

    inputsig = pds.read_csv(folder+"/input.txt",sep=" ",header=None)

    inputsig.columns=[ "CH{}".format(i) for i in range(inputsig.shape[1])]

    outputsig = pds.read_csv(folder+"/output_fx.txt",sep=" ",header=None)

    outputsig.columns=["Tstamp"]+[ "CH{}".format(i) for i in range(outputsig.shape[1]-1)]

    f, axarr = plt.subplots(1,2,figsize=(14, 6))

    (outputsig.filter(regex="CH*")- inputsig*0.8912)[150:].plot(ax=axarr[0])

    axarr[0].legend(loc='upper right')

    (outputsig.filter(regex="CH*")[:100]/0.8912).plot(ax=axarr[1])

    axarr[1].legend(loc='upper right')

    plt.show()

```
