\subsection{Johnson \section{Johnson  Noise} To perform the Johnson Noise Experiment, we used the Noise Fundamentals devices and two digital multi-meters. Our settings for the Noise Fundamentals devices were as follows: $10K$ ohm resistor, we used a Gain 1 (G1) of $600$ for all values that comes directly from the Noise Fundamental device, a Gain 2 (G2) of $1000$ for all values, we used a room temperature of $295$ degrees Kelvin, and we varied the high and low pass filters' frequency for each data set in order to vary the bandwidth. In Table 1, you can see how we varied the low pass filter (f2) and the high pass filter (f1) in order to change the bandwidth. The values are taken from the multi-meter after going through the filters, gain, and multiplier. All of the values are in mV; we took $36$ sets of data points.
