Feature Extraction in Signals using Wavelets

Decompose real-world signals into time-varying frequency components using wavelet transform in MATLAB®, and extract relevant features for further processing.
Use the Discrete Wavelet Transform in MATLAB® to extract spectral features from real-world signals. The goal of this demo is to demonstrate how you can use wavelet transform to extract R waves from an EKG signal to enhance peak detection and compute heart rate. Refer to Feature Detection Using Wavelets - Part 1 for more information about how wavelet transform can be used to identify spectral features.
