Signal processing basics – the scenario is, its a new day and your boss tells you ‘we need to do some testing on that new prototype… you went to University, can you run a vibration test and show me the data? we need to know how it vibrates and will it fall apart’…. what are they on about.
Whilst it is easy to get results with a modern data acquisition and analysis system, they work pretty much ‘out of the box’, sadly there are many pitfalls that means your grapahical data is useless and meaningless (not that your boss will know that!!). Understand signal processing basics and you have a chance to get some useful data.
We aim to give you a practical insight into the following, we will NOT blind you with maths and formulae, we will show you lots of videos and pictures!! After decades of testing we understand which basics help you understand what you are doing.
- The difference between analogue signals and digital signals
- Analogue to digital signal conversion
- Errors introduced
- Windows (not the type you look through!)
- Sampling and sample rates
- Aliasing (using anti-aliasing filters)
- Overlap
- Analysis types
- The time domain and the frequency domain
This course can be run on site and lasts anything from 2 to 4 hours, depnding on delegate interaction and level of experience.
We also run a more comprehensive course at locations around the UK which is a full day, keep checking here for details, or visit the website www.vibration-test.com for available courses
