摘要: A closed loop modulated Hopping Discrete Fourier Transform (mHDFT) based quadrature detector is proposed to estimate the various vibration parameters. The hopping DFT efficient way of calculating N samples. system poles always reside on unit circle and as there no twiddle factor involved in feedback filter so accumulation error while This algorithm implemented Phase Locked Loop design for non contact type estimation. detection accuracy estimator very high even low frequency signals.
