Rice University, Houston, TX - May 16, 2018
Sampling rates? Windows? Leakage? No problem! Learn how to take meaningful and correct digital data in any situation at our seminar at Rice University in Houston, TX.
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?
