Bad Fast Fourier Transfer (FFT) data captures can cause you to misunderstand the true performance of your analog-to-digital converter (ADC). Some engineers like to coherently sample and capture data ...
A new algorithm performs Fourier transforms using a minimal number of samples. The fast Fourier transform, one of the most important algorithms of the 20th century, revolutionized signal processing.
I recently had a discussion about measuring noise density (i.e., op amp noise) with a digital oscilloscope. While we certainly use oscilloscopes to measure time domain noise, as can be seen on nearly ...
