\label{fig:JohnsonSetUp}  From left to right: 1) \textbf{1)}  Low Level Electronics. Electronics (LLE).  This instrument provides the $\textrm{R}_\textrm{in}$ (the $10\textrm{k}\Omega$ and $1\textrm{k}\Omega$ resistors in this experiment) and an initial gain of $\times600$ gain, G1,  when using $\textrm{R}_\textrm{f}=1\textrm{k}\Omega$. $\textrm{R}_\textrm{f}=1\textrm{k}\Omega$ that amplifies the signal to a big enough voltage for the High Level Electronics (HLE). \textbf{2)} High Level Electronics. The high pass and low pass filters of this instrument provides a bandwidth frequency ($\Delta f$) which will eliminate all parts of the incoming signal that are out of that frequency range. Then, the filtered signal is again amplified by G2. Finally, the signal goes through a multiplier. \textbf{3)} Only the upper right DMM is used in this experiment, with which the final signal was read.
