ABSTRACT
This chapter briefly overviews the digital signal processing with an outline of introduction and importance of biomedical signal processing. Biomedical signal processing plays an important role in analysis of human body. For this, bioelectric potential needs to be recorded digitally and processed through digital processing system. In general, all the real-world signals are analog in nature. Initially, these analog signals are converted into digital signals, and then digital filters and other signal processing techniques are applied over them. Same is also followed in case of biomedical signals. A brief overview of this conversion process is also given in this chapter. Mainly, this chapter explores about generation process, recording, signal processing and common problems of electrocardiogram (ECG), electroencephalogram (EEG), electromyogram (EMG), and electrooculogram (EOG) signals. Real signals are also visualized that are taken from known datasets. This chapter provides a good base for any beginner in the field of biomedical signal processing.
