i need a program to calculate a frequency in a signal. for that i was thinking to apply the fft algorithm. in this first stage i want to take the values of the signal from an excel table. the frequency must be saved in an excel table too(in a different excel file from the input), together with the input values. the output values must be print in a graphic together with the input (in a different color). in this grafhic the x axes will be time (that is supply with the input excel.) after done this i will need to make the same for 5 different values and print the graphs at the same time. all the graph curve must be hidden or not from the graphic (with a check box). this will be not the final program and i think that many complex modifications will be made in the future and i think will be made by the person who start the project.
