- Files you are using:
- opamp_file.grc
- test.dat
- Open "opamp_file.grc", and change parameters according to the setting in part I. You need to set the LPF cutoff as well.
- In "File Source" block, load "test.dat" converted from "test.csv" in the above step.
- Run the program, you should see similar outputs from part II. If the console window is empty, the signal is unable to be detected properly. Redo the recording and conversion.

Now, with step I - IV, you should be familiar enough with the SOP. However, this is the case when no interference has been involved. Repeat the above steps with interference enabled, record a few signals with different interference amplitudeamplitudes, and you can use these to determine a good level of suppression of your LPF.
