Spectrum analyzer types are distinguished by the methods used to obtain the spectrum of a signal. There are swept-tuned and fast Fourier transform (FFT) based spectrum analyzers: • A swept-tuned analyzer uses a superheterodyne receiver to down-convert a portion of the input signal spectrum to the center frequency of a narrow band-pass filter, whose instantaneous output power is recorded or displayed as a function of time. By sweeping the receiver's center-frequenc… WebMay 27, 2024 · A new FFT code: FOG Fast Fourier Transform Optical Simulation of Gravitational Wave Interferometers, Wave Advanced Detector Workshop (GWADW 2012), 2012.
