Explore MATLAB source code curated for "带阻滤波器" with clean implementations, documentation, and examples.
ECG signal preprocessing techniques using high-pass filter for respiratory baseline drift removal and band-stop filter for power line interference cancellation, with computational efficiency comparison between filter implementations
This resource covers the design of bandpass and bandstop filters using a Butterworth filter package. The package includes: bendpass.m (bandpass filter implementation), bendblock.m (bandstop filter algorithm), SE144.wav (input audio file for processing). Requires placing SE144.wav in C: drive root directory. Processed outputs: bendpass.wav (bandpass-filtered audio saved to C:\) and bendblock.wav (bandstop-filtered audio saved to C:\).
