The goal of spectrum analysis is often to determine the frequency content of an analog (continuous-time) signal ; very often, as in most modern spectrum analyzers, this is actually accomplished by sampling the. analog signal, windowing (truncating) the data, and computing and plotting the magnitude of its DFT. It.

The shape of the amplitude spectrum is determined by the function sin( f ) f π τ π τ . the single rectangular pulse of width τ contains all frequencies between 0 and ∞. the relative amplitudes (ignoring the overall amplitude factor) of these frequencies is given by the function sin( f ) f π τ π τ .
Read moreWhat is Fourier amplitude spectrum?
The Fourier amplitude spectrum FS(ω) is defined as the square root of the sum of the squares of the real and imaginary parts of F(ω) . Thus: [2] Since a(t) has units of acceleration, FS(ω) has units of velocity. The Fourier amplitude spectrum is of interest to seismologists in characterizing ground motion.
Read moreAre amplitude spectrum and frequency spectrum same?
Any signal whose amplitude is a function of time has a corresponding frequency spectrum . When the signals are viewed in the form of a frequency spectrum, certain aspects of the signals or the underlying processes producing them are revealed.
