摘要

提出了一种基于空间对称性分析换能器效应的新方法。为此，需要具有不同空间取向的多种工作模式的对称换能器。扫描所有模态后得到的响应写成傅里叶级数，其中每个系数对应于一个特定的对称关系。所有具有不同对称关系的换能器效应都可以直接从空间频谱中提取出来。以16触点对称霍尔极板为例。

Fourier analysis based on spatial symmetry in transducers

A novel approach to analyze transducer effects on the basis of their spatial symmetry is presented. To this end, symmetric transducers with multiple modes of operation with different spatial orientations are needed. The response obtained after scanning all modes is written as a Fourier series, of which each coefficient corresponds to a particular symmetry relation. All transducer effects with different symmetry relations can be extracted directly from the spatial frequency spectrum. A 16-contact symmetrical Hall plate is used as an example.<>
