title = "A new processing method for SAW resonator torque response signal",
abstract = "The response signal is of narrow band, high frequency, low SNR (Signal to Noise Ratio) and transient attenuation. Torque applied to the shaft can be acquired from changes of the center frequency. The resolution of FFT (Fast Fourier Transform) method is limited by sampling length. MLE (Maximum Likelihood Estimate) or LSE (Least Square Estimate) is time-consuming. In this paper, GA (Genetic algorithm) is employed to estimate parameters of the sensing signal. Before GA, response signal is simplified by Hilbert envelope-demodulation. After demodulation, the resonance frequency can be obtained directly in time domain by GA. Results indicate this method estimates the frequency more accurately.",
