研究逼近网络原理的连续小波变换的SI(switched-current)实现方法。利用网络函数逼近理论,将连续小波变换转化为双二次函数并联电路结构,并以SI电路技术实现任意一维连续小波变换。本文以Marr小波为例。 The study of the switched-current (SI) method of approximation network theory for continuous wavelet transform. Using the theory of network function approximation, the continuous wavelet transform is transformed into a biquadratic parallel circuit structure and an arbitrary one-dimensional continuous wavelet transform is realized by the SI circuit technology. In this paper, Marr wavelet as an example.
