Abstract

A new method for multidimensional digital signal processing for Printed Circuit Boards (PCB) testing is described. The considered method comes to solve such problems as competition and synchronization, which are present in the multidimensional signals processing. The solution is achieved by performing in parallel all operations, replacing the analog-to-digital conversion (ADC) with differentiation operations and analyzing the signal variation rate based on the Fuzzy logic elements. As a result of these operations, using digital integration models, binary code streams are obtained that allow the reconstruction of the signal shape. Mathematical models applied for the transformation and processing of multidimensional signals are presented. The designed system for the multidimensional signal processing consists of a computing unit, the test signals generator, the data storage unit, the Printed Circuit Board with nodes for test signals application and retrieval, and finally the processing elements for differentiation and analysis based on Fuzzy logic.

印刷电路板检测的多维数字信号处理

提出了一种用于印刷电路板测试的多维数字信号处理新方法。该方法解决了多维信号处理中存在的竞争和同步问题。该方案通过并行执行所有运算，用微分运算取代模数转换(ADC)，并基于模糊逻辑元素分析信号变化率来实现。作为这些操作的结果，使用数字集成模型，获得二进制码流，允许重建信号形状。提出了用于多维信号变换和处理的数学模型。所设计的多维信号处理系统包括计算单元、测试信号发生器、数据存储单元、用于测试信号应用和检索的带有节点的印刷电路板，以及基于模糊逻辑的处理单元进行区分和分析。
