چکیده انگلیسی
A keep-it-simple (KIS) solution is introduced that interpolates a signal up to an arbitrary accuracy. It consists of interpolating the complex envelopes at the output of a perfect-reconstruction filter-bank: if K subbands are used, the proposed interpolation scheme is shown to have a similar figure of merit as if the signal was initially oversampled by factor K at the acquisition stage, yet without the storage burden implied by the latter method.
► High-fidelity interpolation of vibration and acoustic signals.
► Is crucial in many condition monitoring applications.
► An original and very simple solution is proposed.
► It consists of interpolating K subbands at the output of a PR filter-bank.
► Dramatically reduces interpolation error.
