In order to understand if our values seem reasonable, we wanted to perform another Johnson Noise test with a different resistance in order to see if we can generate the Boltzmann Constant. For our values, we used a resistance of $1000$ ohms, a temperature of $295$ Kelvin, a Gain 1 (G1) of $600$, a Gain 2 (G2) of $1000$, and we varied the low and high pass to change the bandwidth. In Table 3, you can see the results from this second trial. All of the values are in mV and came from the multi-meter reading the voltage after it had gone through both gains, both filters, and a multiplier. We analyzed this data in the same way we did our first Johnson Noise data, we found the $V^2$ directly from the data given by the multi-meter and found the bandwidth (\Delta f) ($\Delta f$)  found by varying the different filters.
