Research on Measurement Unit with Self-Check Parameters of Piezoelectric Transducer
摘要
Abstract
It is natural to develop a new method to measure the resonant frequency, the anti-resonant frequency and the static capacitance. Based on the π network, a new method to do these works is brought out. And the hardware and software to measure the parameters are designed. Finally, through the measurement of the unit, the basic measure of the piezoelectric transducer can be done.关键词
