• In order to reveal unsteady features of gas-solid two-phase flow in both Fourier and physical spaces, the wavelet multi-resolution analysis, employed to analyze the experimental data of the wall pressure-time signal, were discussed for different wavelet bases. It is evident that the minimum-bandwidth discrete-time (MBDT) wavelet basis offers superior frequency-domain properties to Daubechies wavelets given a filter of the same length.
