摘要：
The discrete wavelet transform (DWT) has a very wide and important application in digital signal processing. Daubechies order 4 wavelet transform (db4) is elected to discuss in this work. The advantages of DWT are analyzed, and a three-level Mallat algorithm is implemented in this paper, and db4 low-pass and high-pass filters are selected in each level. An orthogonal two-channel db4 filter of Lattice structure is selected and implemented, and the improved structure of the Mallat is designed in this paper. In order to verify the DWT which is designed, the EEG data is elected in this paper. The design is implemented in Verilog and simulation is performed on the Modelsim, and the FPGA implementation is verified on ISE13.3 platform.
