| Abstract: | The implementation of Morlet wavelet-transform (WT) using switched-current (SI) technology was presented in this paper. The method with the advantage of simple implementation was helpful to manufacture integrated chip. SI bilinear integrators were used to synthesize Gaussian band-pass filter by using leapfrog to simulate RLC passive filter. Then Morlet wavelet transformation filter was synthesized. It gave a new way for wavelet-transform. |
