In the early 1990's we developed a special computer program called UW DigiScope to provide a mechanism for anyone interested in biomedical digital signal processing to study the field without requiring any other instrument except a personal computer. There are many digital filtering and pattern recognition algorithms used in processing biomedical signals. In general, students have very limited opportunity to have hands-on access to the mechanisms of digital signal processing. In a typical course, the filters are designed non-interactively, which does not provide the student with significant understanding of the design constraints of such filters nor their actual performance characteristics. UW DigiScope 3.0 is the first major update since version 2.0 was released in 1994. This paper provides details on how the new version based on MATLAB! works with signals, including the filter design tool that is the programming interface between UW DigiScope and processing algorithms.
20世纪90年代初，我们开发了一个名为UW DigiScope的特殊计算机程序，为任何对生物医学数字信号处理感兴趣的人提供一种学习该领域的机制，除了个人计算机外无需任何其他仪器。在处理生物医学信号时会用到许多数字滤波和模式识别算法。一般来说，学生实际接触数字信号处理机制的机会非常有限。在典型的课程中，滤波器是通过非交互式方式设计的，这无法让学生深入了解此类滤波器的设计约束及其实际性能特征。UW DigiScope 3.0是自1994年发布2.0版本以来的首次重大更新。本文详细介绍了基于MATLAB的新版本如何处理信号，包括作为UW DigiScope与处理算法之间编程接口的滤波器设计工具。
