摘要

本文介绍了一种用于分析变磁阻传感器矩阵信号的新型仪器。信号处理技术是基于FFT评价的。主要的目标是紧凑，更重要的是，在短时间内进行阐述。特别是，假设U测量石灰约300p，可同时处理多达I个不同传感器的信息。实验结果表明，分辨率在+0.2 pm量级。

A multichannel dsp-based dvrt instrument

Am - This paper presents a novel instrument for the analysis of signals coming from matrix of DiJprential Variable Reluctance Transducer. The signal processing technique is based on FFT evaluation. The muin objective is compactness and, more imporlant, a short elaborafion time. In particular, information from up to I I different sensors can be simultaneously processed, supposing U measuring lime of about 300p. Experimenial resalts show a resolution in the +0.2 pm order.
