... static deformation in body-fixed coordinates while the backward term oscillates twice per revolution (e.g., see Ref. [ 14 ]). Coquad or complex demodulation produces complex amplitudes and indeed, Fig. 11 traces the real versus imaginary amplitudes (or orders) showing that phase changes rapidly...

... positioning systems lag synchronization phase synchronization chaotic synchronization chaotic modulation demodulation Recently, there have been intensive studies of ultra-wide-band communication systems. The interest in such systems is due to the various potential applications of ultra-wide-band...

... ). Then, the envelope is computed from a time decomposition only. Finally, the Fourier spectrum of the envelope allows us to visualize the characteristic frequencies of the damage. Thus, we implemented a simple and fast tool of detection. We call this method adapted-wavelet demodulation (AWD) (Fig. 1...
