The Discrete Fourier Transform
... we look at the mathematics and algorithms of the Fourier decomposition, the heart of the DFT. The Family of Fourier Transform Fourier analysis is named after Jean Baptiste Joseph Fourier (1768-1830),a ... found the desired algorithm. The other samples in the frequency domain are calculated in the same way.This procedure is formalized in the analysis equation, the mathematical wayto calculate the ... decomposition, analysis, the forward DFT, orsimply, the DFT. If you know the frequency domain, calculation of the timedomain is called synthesis, or the inverse DFT. Both synthesis and analysis can...

After calculating the complex DFT (via the FFT, of course), the spectra are separated using the even/odd ... discovered the FFT at the right time, the beginningof the computer revolution. The FFT is based on the complex DFT, a more sophisticated version of the realDFT discussed in the last four chapters. These ... of the frequency spectrum. Therefore, the frequency spectra are combined in the FFT by duplicating them, and thenadding the duplicated spectra together.In order to match up when added, the...

In the ... ScalingTo make the analysis and synthesis equations undo each other, a scaling factormust be placed on one or the other equation. In Table 31-1, we have placed the scaling factors with the analysis ... After the FFT calculation, the spectra of the two signals are separated by an even/odd decomposition. The Family of Fourier TransformsJust as the DFT has a real and complex version, so do the other...

... EIGHT FOURIER ANALYSIS In this chapter, Fourier analysis will be discussed. Topics covered are Fou-rier series expansion, Fourier transform, discrete Fourier transform, and fast Fourier ... TRANSFORMS Fourier series links a continuous time signal into the discrete-frequency do-main. The periodicity of the time-domain signal forces the spectrum to be dis-crete. The discrete Fourier ... Hz') The plot of the noisy signal and its spectrum is shown in Figure 8.8. The am-plitude of the noise and the sinusoidal signal can be changed to observe their effects on the spectrum....
