 As in the first experiment, run a single frequency sweep with scope channel 2 connected through coupling capacitor C<​sub>​4</​sub>​ to the collector of Q<​sub>​1</​sub>​. To measure the response of the high pass input filter, connect scope channel 2 through coupling capacitor C<​sub>​4</​sub>​ to the base of Q<​sub>​1</​sub>​. Be sure to export the data to a .csv file for further analysis in either Excel or Matlab. Compare the response curves with what you measured for the circuit in figure 2. Try different combinations of values for C<​sub>​2</​sub>,​ C<​sub>​3</​sub>​ and R<​sub>​4</​sub>​ to see how the frequency response changes. As in the first experiment, run a single frequency sweep with scope channel 2 connected through coupling capacitor C<​sub>​4</​sub>​ to the collector of Q<​sub>​1</​sub>​.
