Short course/CPD

Advanced Signal Analysis

with emphasis on mechanical systems: theory and exploration

 

Course date: Please enquire

Course overview

This unique course has been specifically designed to meet the practical need of engineers in applying and developing signal analysis tools for mechanical systems. The course presents the basic fundamentals of signal analysis, as well as advanced time-frequency signal analysis methods with application to complex mechanical systems. The course will also stress advantages and limitations of various signal analysis techniques and their relevance to specific applications and tasks. The choice of analysis parameters needed for the use of commercial signal analysis packages will be discussed. Actual signal analysis tasks will be both demonstrated and applied by the participants, using GUI base software from the latest textbook by S Braun, Discover Signal Analysis, An Interactive Guide for Engineers (Wiley 2008). Participants will receive copy of the book on completion of the course.

This course will be of interest to people who already have basic background in signal processing. It is desirable, although not essential, that delegates have an elementary knowledge of the subject such as that provided by the Cranfield short course Practical Signal Processing.
