 One can connect an audio mixer (with a 500 kOhm resister) and oscilloscope probes to three different points. X and Y are at the connection of the capasitor and the poti. The third one (Z) is on the gyrator board.\\ One can connect an audio mixer (with a 500 kOhm resister) and oscilloscope probes to three different points.
