Digital Data Acquisition and Processing Seminar

Sampling rates? Windows? Leakage? No problem!
Learn how to take meaningful and correct digital data in any situation.

Siemens PLM Software, Troy, MI - December 7, 2017

This free seminar can help you answer questions like:

  • What causes ground loops and how do I avoid them?
  • How does a differential transducer improve my data quality?
  • When do I need to apply a window to my data? How do windows distort my data, and how do I correct for this?
  • When should I use a Power Spectral Density function?
  • How do filters effect my data?
