Overcoming Noise in Data Acquisition: The Seven Deadly Sources, and How to Improve the Measurement Performance of Any System - February 23, 2010
Have you ever captured noisy data to your PC, having to then use software to "massage" the data to try and yield useful results? If so, this seminar will outline the basic sources of electrical noise in data-acquisition systems and explain methods for eliminating them.
PCs today have become the primary interface to Data Acquisition Systems, to the extent that actual data acquisition components “under the hood” have sometimes been improperly designed or misunderstood. Have you ever captured noisy data to your PC, having to then use software to “massage” the data to try and yield useful results? This seminar will outline the basic sources of electrical noise in data acquisition systems, and systematically explain practical methods to eliminate each one.
Topics Covered:
- Data Acquisition Overview
- Quantization Noise
- Internal A/D Noise
- Power Line Noise
- Time Skew
- Aliasing Noise
- Common Mode Noise
- Radiated Noise
- Application Examples
