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.

Typically, a data processing frame might comprise 1,024 contiguous samples. FFT If all you needed was the spectrum corresponding to the modulation, the frame of digitized data could be fed to a DSP ...

In the process of debugging and validating both digital and RF designs, the oscilloscope Fast Fourier Transform (FFT) function and a variety of other math functions can prove valuable to designers ...

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 ...

You probably have at least a nodding familiarity with the Fourier transform, a mathematical process for transforming a time-domain signal into a frequency domain signal. In particular, for computers, ...

FFT-EM is an innovative method that represents a combination of FFT and EM techniques such as scanning electron microscopy (SEM). The technique is often used to determine the interior and surface ...
