Digital Signal Acquisition and Processing

Event | 10 September 2019 8:00 AM EDT
Siemens PLM | 5555 New King, Troy, MI 48098

Sampling rates? Windows? Leakage? No problem!

We invite you to join us for an informative and educational day covering all aspects of Digital Signal Acquisition and Processing on September 10, 2019 in Troy, MI.

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?
