\subsubsection{Johnson noise in $10K$ Ohm Resistor}  Refer to electronics setup photo Fig.~\ref{fig:JohnsonSetUp} for the set up of our apparatus. Our settings for the Noise Fundamentals devices were as follows: for the $10\textrm{k}\Omega$ resistor, we used a Gain 1 (G1) of $\times600$ for all values that comes directly from the Noise Fundamental device, a Gain 2 (G2) of $\times1000$ for all values, we used a measured value for  room temperature of $295.15$ 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. You can see all these values in Table 1.
