magnitudes of the varied resistor vr varied capacitor vc varied inductance vi varied attenuator va are dependent on the loads and the impedance of the other connected devices respectively and the thermopile plays a nominal role of fast switch and follows the temperature when it changes for the positive type as the shock comes the temperature is getting high the correspondence impedance becomes a proportionately large value after the shock is removed the temperature is going down the impedance also returns to the nominal area and waits for the next cycle to come in the transition process how fast the switch works on is dependent on the natural frequency of material i e what kind of material made the bandwidth of frequency response under 10 0 ghz is now capable of using and more strictly related to the realistic implementation issues for example sige gaas inp if the gradient of temperature is positive negative the frequency of switching should be speeded up slowed down and transit into some kind of equivalent state between temperature change and impedance increase decrease when the shock coming the impedance contributed from the electrical part of dadam has been self tuning more and more again and.
