An approximate formula is derived which helps the practical computation of the maximal voltage peak.
The results show that, among the stator coils, the highest voltage peak appears across the coil next to the input; thus, this first terminal-end coil is subjected to the highest voltage stress.
The voltage peak during an AP followed exactly the Nernst potential of potassium over a range of external potassium concentrations from 5 μM to 0.2 M.
For this reason the voltage peak is higher in the first case, and the noise width is larger in the second case.

Sothat, the emphasis of this paper is to discuss the solving process of this kind ofcircuit with ring-core, to which a squarewave voltage is supplied. Owing to a qui-te high resistor inserted in the excitation circuit, the magnetic modulator is exci-ted by square-wave voltage in form, but actually it's excited by pulse current.Moreover, from the condition of constant current source, the expressions of evenharmonic flux has been derived by means of even illustrated analysis. The resultshows the peak value of output voltage modulated by the signal field H_0, increasesin one direction with H_0, but decreases in the opposite direction. Therefore, it pro-vides the basis for the use of peak-difference demodulator.
