Résumé

Measuring means extracting information from acquired signals. Either in the frequency or in the time, mathematical processing tools are applied to get information from measurement signals. It is usual, when processing measurement signals in the frequency domain, the application of Fourier analysis, mainly through Fast Fourier Transform (FFT) algorithms. Nevertheless, there are other digital signal processing tools that can overcome FFT performance in computation time or accuracy, and they can be very useful when extracting information from measurement signals. This paper presents some powerful mathematical tools and it shows how useful they can be, when measuring hermetic compressor speed through externally-measurable quantities.
