Abstract
This paper presents a comparison between two algorithms for sinusoidal signal characterization applied to QCM impedance measurements. These algorithms are the zero crossing and peak detection method and the 7 parameters sine-fitting method. Simulation and experimental results from both methods are shown in order to determine which method provides the best performance in terms of accuracy. Obtaining a precise value of the QCM impedance depends directly on the precise measurement of the amplitude ...
