Wavelet Transform Using DSP Microcontroller
- 205 Downloads
The wavelet transform is used especially for analyzing of the signals buried in noise or when the discontinuities through the signal is the subject of interest. A method of pattern recognition of the PCG signals with the help of the wavelet transform can be implemented by the computing of Shannon entropy of the signal, at every decomposition level.
