Decomposition … WebDec 29, 2024 · Moreover, bior2.6 wavelet produced the best SNR on all decomposition scales, followed in turn by bior2.4, and bior2.2. Therefore, when the length of low-pass decomposition filter sequence falls in a certain range, the SNR is proportional to the sequence length. If the sequence is excessively long, the SNR cannot be further improved.
