Tripple Slope Generator is my TSG circuit to clarify that part...in his hearing patent Puharich states the need to auto tune due to the different capacities of the human head ...he states the use of high inductance coils and how the resonate frequency changes when using different types of electrodes...the other circuit, i think figure 2 was a variable type generator for use with all his different type of electrodes is that right? Wich one does he use as the input to component 2 of his wfc?

If you put a capacitor that is 10 times biger than the other in series basically you end up with smaller capacitance than the smaller capacitor... if you get the signal to oscillate only with the head capacitance you will get a changing frequency... if you get a capacitive coupled drive in this way you get a stable resonance that will fluctuate not much than 10 percent... for example..

This is what im getting out of his figure 3 circuit...its a negative voltage tho.
