Many of today's digital oscilloscopes include fast-Fourier-transform (FFT) capability for frequency-domain analysis. This feature is especially valuable for oscilloscope users who have limited or no ...
The Zoom FFT is interesting because it blends complex down conversion, lowpass filtering, and sample rate change through decimation in a spectrum analysis application. The Zoom FFT method of spectrum ...
Many science and engineering applications require an accurate frequency spectrum or Fourier transform of a signal. The Fourier transform of a sequence of samples of a signal is shown in Equation ...
The FFT (Fast Fourier Transform) is rightfully regarded as the most important numerical algorithm of our lifetime. Whether it's used to monitor signals coming from the depths of the earth or search ...
