Abstract:
The spectral analysis is an important technique in the signal processing; it shows signal characteristics in frequency domain. The aim of the project is to review the state of art of the real-time spectral analyzers and their applications. Throughout this work, a suggested techniques for the implementation of spectral analyzer has been introduced. Also, an experimental system has been designed using the multiple techniques. The spectral analyzer system, which is used in this study, is implemented by three techniques: the first one is Fast Fourier Transform technique (FFT). The second one is Integral Pulse Frequency Modulation (IPFM) and the third is zero-crossing techniques. A sort of comparison has been made, showing that these techniques are considerably efficient techniques for small time scale (Real-Time). The characteristics of signal has been measured for the three techniques and the values of error are discussed. The real time spectral analysis is achieved by using the three methods mentioned before, they are implemented using a high speed hardware also using a computer of a high speed performance. This system has been operated, and experimented in a wide range of applications. In this respect, DSP and Turbo C programming package are the principle of the simulation tool performance.
