WebThe extension provides a frequency continuum of components using an infinite domain of integration: Fourier transform (Eq.1) Here, the transform of function at frequency is denoted by the complex number , which is just one of several common conventions. Evaluating Eq.1 for all values of produces the frequency-domain function. WebFrequency Domain As all signals are acquired in the time domain, a waveform must be transformed to analyze the data in the frequency domain. There are several standard methods to do so, but perhaps the most popular method is the fast Fourier transform (FFT). Fast Fourier Transform
