Webwas equipped with FFT filters for narrow bandwidths. Multiple narrowband FFTs were concatenated to a trace representing the selected frequency span. As the computing time for the FFTs was small compared to the settling time for narrow RBW filters, the FFT method provided a great speed advantage over the traditional sweep method. WebOct 28, 2024 · More about FFTs. The Fast Fourier Transform, or FFT, is a mathematical technique that deconstructs a complex waveform into its component sine waves. Presented with a segment of data which represents the amplitude vs. time relationships of a complex waveform, an FFT will derive two sets of results: the amplitude spectrum (amplitude vs. … how a deep fryer works https://mihperformance.com
