Learn how digital signal processing (DSP) principles impact the measurements you make every day.
Terms like FFT, leakage, antialiasing, windows, and spectral lines are common in signal analysis, but understanding how they affect real-world measurements can be challenging. In this webinar, ATA Engineering’s experts explain the relationships among the fast Fourier transform (FFT), antialiasing, leakage, and sampling criteria, helping you better interpret and improve your measurement results.
This session provides an overview of key DSP concepts, including Rayleigh and Nyquist sampling criteria, the causes and effects of spectral leakage, and practical techniques for reducing leakage through windowing. We also discuss the corrections required when using windows and how these choices influence measurement accuracy.
Using measured data and real-world examples, we demonstrate how DSP concepts apply in practice and examine the tradeoffs between time and frequency resolution. Whether you are new to signal processing or looking to refresh your knowledge, this webinar offers practical insights that can help you make more informed measurement decisions.
