In this paper the accuracy of some digital signal processing algorithms for distance measurements by ultrasonic sensors is analysed and discussed. The authors have fixed their attention on three time-frequency analysis technique (Hilbert, Wavelet and Short Time Fourier Transforms), discussing both the systematic error (due to the finite time resolution) and the random error (due to noise).
