Fast Fourier Transform (FFT)
eXpert FPGA DSP Feature for CompuScope Digitizers

Fourier Transform analysis is a powerful signal processing technique used in a wide variety of applications. Typically, Fourier transformation of time domain waveforms requires the execution of the computationally intensive Fast Fourier Transform (FFT) algorithm on a host PC.

Utilizing the eXpert FFT Firmware on a GaGe CompuScope Digitizer allows users to conduct computationally intensive FFT algorithms completely on the digitizer’s onboard FPGA with absolutely no host system CPU loading, allowing the host PC to handle other tasks in parallel.
