Digital Fourier Analyzer

Digital Fourier Analyzer: The basic principle of a Digital Fourier Analyzer is shown in Fig. 9.14. The Digital Fourier Analyzer converts the analogue waveform over time period T into N samples. The discrete spectral response Sx(kΔf);k=1,2,…,N which is equivalent to simultaneously obtaining the output from N filters having a bandwidth given by Δf=1/T, is obtained by […]
