How is signal processing used in biomedical applications?
Biomedical signal processing involves acquiring and preprocessing physiological signals and extracting meaningful information to identify patterns and trends within the signals. Sources of biomedical signals include neural activity, cardiac rhythm, muscle movement, and other physiological activities.
What are the types of biomedical signals?
There are several types of biomedical signals, as EMG, electroencephalogram (EEG), electrocardiogram (ECG), electrooculogram (EOG), gait rhythm (GR) and magnetic resonance imaging (MRI).
What are the difficulties encountered in biomedical signal acquisition and analysis?
The problems encountered in the analysis of biomedical time series are due to the total data length, the non stationarity of the time series and the non linearity of the underlying physiological processes.
What is biomedical signal Analysis?
Biomedical signal analysis is employed to remove the noise, create accurate signal model and analyze its components, extract features for decisive function or dysfunction, and predict future pathological or functional events in brain, heart, or muscle (Muthuswamy 2004).
