| Περιγραφή: | Digital Signal Processing discussed in this thesis is concerned with the transformation of signals or complex wave forms From time domain to frequency domain and vise-versa, implemented on microcomputer systems. The primary principles are: speed of transformation, ease of usage as an application program, capabilities of graphics displaying transformed data (such as power spectrum analysis), storing these data onto record files, and capability of using these data Files and programs with other application programs. We begin by discussing briefly, the concepts of Fourier theory, Discrete and Fast Fourier Transform, algorithms of Fast Fourier Transform and bit-reversal. Then we implement these algorithms using the C-language, which has high-lights Cand is the reason why we chose this language), that are described in Chapter II. We then modify some parts of the algorithm, improving the speed of transformation, and achieve an FFT 286-point application program. For Power Spectrum Analysis, we make another graphics display program which is written in True Basic language, a good language for graphics purpose. We also make a file interface program to interface these programs and data files with other application programs such as MADCAP, made by Withman Engineering Inc. In the end, we will achieve the speed of transformation of a 256-point FFT in 1 second, which is almost as Fast as if it was written in assembly language. The program gives ease of usage and displays results in an easy Format to read. We will then apply a program which will decipher the various points showing the power spectrum in a high resolution graphics display. |
