Analog implementation of Marr wavelet transform with switched-current technique
Yigang He · Journal of Circuits and Systems · 2009
An analog method for the implementation of Marr Wavelet Transform using Switched-Current(SI) is proposed.Taylors's theoem is used to approximating Marr wavelet transform in frequency-domain,and the mathematical model is realized in circuit by SI which has many advantages such as systematization and modularization.One channel of Marr wavelet is took as an example to indicate the feasibility of this design method.
