| Abstract |
When capturing transient signals, the maximum recording time of the measurement is limited
by the high sample rate used to preserve input signal details. To obtain a maximum recording time
keeping the details an adaptive compression must be performed. Such a method is proposed in this
paper. The method is based on the use of the discrete wavelet transform. To optimise the compression
ratio a criteria for the matching of the wavelets mother with the input signal is proposed. This
matching problem is very important in the wavelet's literature. The correspondent wavelets mother
searching method is described. Some simulations results are described. The superiority of the
proposed compression method is proved. |
