摘要:AbstractKnowledge of basic principles and concepts in time series analysis is fundamental to system identification education; however, this topic is not part of the traditional background for many engineering students. Interactive software tools, on the other hand, have proven as particularly useful techniques with high impact on education. To address this need, this paper describes a collection of interactive software tools (ITTSAE, ITTSAE-TSG and ITTSAE-TSA) that have been developed to assist in teaching and learning time series analysis concepts in the time domain. The tools have been developed with Sysquake, a MATLAB-like language with fast execution and excellent facilities for interactive graphics, and are delivered as a stand-alone executables that are readily accessible to students and instructors. The basic functionality of the tools and an illustrative example on the use of the software are presented.
