【Abstract】 It is proved that a perfect reconstruction system can be constructed by a biorthogonal compact support wavelet given the condition of constructing a perfect reconstruction system by a biorthogonal compact support wavelet and impulse responses of filters in filter bank. The physical implement of this filter bank is based on above conclusion.更多还原
