Single Pole Case: Turn the system into a simple RC circuit by jumping $($bypassing$)$ the inductor, but not the resistor, with a plain wire. Using the myDAQ system, drive the R$-$C system with a $40$ Hz square wave with a $0\mathrm{.}5$ volt offset thus producing a $(0$ to $-1)$ volt negative unit$-$step input.

Display voltage $V_{iz2}$ on the myDAQ oscilloscope channel $1($Ch$1)$ and voltage $V_{\text{s}\text{u}\text{t}}$ on channel $2($Ch$2)$ versus time. Verify the unit$-$step square wave input and that both signals are positive.

Calculate the theoretical system time constant from input$-$output differential equation.

Import the data for $V_{in2}$ and $V_{\text{c}\text{e}\text{s}}$ into the computer using the "Basic$\_$Acquisition" for later analysis. Be sure to note which channel is associated with what voltage. Acquire less than one second of data so more than $1$ complete cycle, but no more than $2$ cycles show $($collect at least $1001$ points and adjust the sampling rate$).$ Be sure to start collecting data when the function is at zero.

Remove the $1500$ resistor, and replace with a $15$ resistor. Acquire a second data set with this lower resistor. When done, put the $1500$ resistor back and take out the by$-$pass on the inductor before taking the next data set.
