The signal transmission theory was applied to circuit network to obtain discrete temperature-time signal transmission model derived by Kirchhoff's law.And then
an iterative algorithm based on voltage and current was proposed
realizing the signal transmission with different temperature change processes.It shows that the amplitude of output signal gradually attenuates with the rise of conductor temperature
by 10% at 300℃.And the amplitude attenuation is more evident due to the coexistence of conductor temperature rise and drop.The corresponding experiment has been conducted
and the results can meet that of proposed model.It provides a new method for improving the accuracy of vibration test signal.
