The notion of multi-resolution analysis to the standard random vibration control approach is presented. It is shown that by implementing the proposed filter bank structure, the output power spectrum converges to the reference spectrum. The technique allows the frequency resolution to be increased at low frequencies and reduces the computation in comparison with increasing the number of samples over the entire frequency range, to achieve the same low frequency resolution. The effectiveness of this method is demonstrated through simulation and a DSP implementation of the technique.
