Lab 6 Overview

1) Compare theoretical and experimental frequency response plots by placing traces on the same axes. Show these for your low-pass filter:

We built an RC low-pass filter with a 430 Ohm resistor and 2.2E-4 Farad capacitor. This should produce a 1st order system with a w_cutoff of 10.6 Hz. Below is our input and output plotted, which was submitted to TFestimate and produced the given Bode plots:

RC, Arduino, Matlab input/output
Blue: input white noise, Red: RC voltage output

Bode from TFestimate
Notice w_c on magnitude plot

Trouble w/Phase response....
As far as the phase response goes, we did not get anywhere close to good results. This was much in part due to the delays in the Arduino and MATLAB.
