| Abstract: | Because of the limitation in traditional method of singularity detection of signal,the design scheme was put forward to detect the precise singularities location of signal with wavelet transform.On the FPGA chip EP2C8Q208 of Altera company,the wavelet db8 is used to realize singularity detection of signal.The experiment results showed that this system has feasibility,real-time,superiority in singularity detection of signal. |
