Are you dealing with dynamic signal like vibration or acoustic? Unlike other measurement such as temperature, humidity, or air velocity, where frequency is less important, running a vibration or acoustic analysis, most of the time (if not always), we will be dealing with frequency parameter.
Unlike other measurement such as temperature, humidity, or air velocity, where we don't have so many issues to consider for determining the acquisition strategy, collecting vibration or acoustic may need us to go through some more details, not only the acquisition strategy, but also what kind of post processing that we are going to perform.
We may also even need to look deeper on the capabilities of our data acquisition system to make sure that it will be able to provide high quality data needed.
This booklet will provide some insights regarding digital signal processing, on what the hardware and software are doing during acquisition process and also data post-processing.
This booklet may provide some ideas also on what kind of small details that we may want to pay attention before making a decision to purchase a data acquisition system together with data post-processing software. Below are some details covered by this booklet.
