Fully Automatic Signal Spectrum Analyser 1.0

This program operates as a signal spectrum analyzer and a distortion meter at the same time. It can accept any numerical data representing few cycles of a signal. The data do not need to be equally separated. At least ten data points per cycle are needed. Higher number of data points will of course produce better results. The main advantage of the program is its ability to automatically detect the fundamental frequency. Any part of the spectrum within the frequency band f1-f2 can be calculated and plotted. The input to the software are the time and signal voltage arrays t,v, the frequency band limits f1 and f2 and the accuracy parameter delta. The out puts of the program are the signal plot, the spectral analysis plot, the frequencies and relative amplitudes of the ten most prominent frequency contents. The software has been successfully used to analyze data obtained from oscilloscope screen pictures of many signals using another program written by the author called oscilloscope.The program can be called through entering[F,A]=spectrum_analysis(t,v,f1,f2,0.001)N.BONE OTHER PROGRAM NEED TO BE PRESENT IN THE WORK DIRECTORYIt is d-deDUmaximad-deDt this is in the Zip file
