I have an hardware related question.
I want to create a measurement set-up so that I can record data for DSP analysis. When searching around I see I have a few different options. The ones I have found are:
- Data acquisition box / interface
- Logic analyzer
- Soundcard (have specific input type (XLR/ TRS-Jack) )
From DSP perspective what are the differences between these types of measuring devices? Specially the difference between a DAQ and a logic analyser?
As Questioned in the comments: what are the parameters i want to measure. Here is the list for now(witch can change later on):
- if possible Ammeter
- different switches for safety sensors(just low and high over time)
- some pulse generators
I'm not sure what the bandwidth is of every signal. But i assume that the maximum bandwidth is from the acceleration sensors. I assume that the bandwidth is
f_max = 10kHz so
f_sampling = 25 or 30 kHz.
