1. Introduction

The rapid advancements in biomedical signal processing have revolutionized the way healthcare data is analyzed and utilized for diagnostics. Biomedical signals, such as electrocardiograms (ECG), electroencephalograms (EEG), and electromyograms (EMG), contain vital information about various physiological processes. These signals, however, are often complex, noisy, and require specialized techniques for accurate interpretation.

Effective biomedical signal preprocessing is fundamental to enhance the quality and utility of acquired data. Signal denoising, baseline correction, artifact removal, and filtering are crucial steps to eliminate noise and artifacts. Various signal preprocessing techniques, such as wavelet transform, Fourier transform, and adaptive filtering, are discussed in this section.

3. Feature Extraction

Feature extraction plays a pivotal role in biomedical signal processing as it reduces the dimensionality of data and highlights relevant patterns. Time-domain, frequency-domain, and time-frequency domain feature extraction methods are explored in this section. Additionally, advanced feature selection techniques, such as Principal Component Analysis (PCA) and Independent Component Analysis (ICA), are discussed to improve diagnostic accuracy.
