Application of Signal Processing in Biomedical Industry

1.  What is Signal Processing?     Signal processing  is an electrical engineering  subfield that focuses on analysing, modifying, and synthesizing signals  such as sound, images  and scientific measurements.   Signal processing techniques can be used to improve transmission, storage efficiency and subjective quality and to also emphasize or detect components of interest in a measured signal. fig. 1. Signal Processing. 1.1 What is Biomedical Signal Processing? Biomedical signals are the recording of the observations of physiological activities of organisms, ranging from gene and protein sequences, to neural and cardiac rhythms, to tissue and organ images. It is the clinical study of the internal body metabolisms, diagnosis of ailments, and detection of diseases using the electronic instrumentation. Biomedical signal processing aims at extracting significant information from biomedical signals. With the aid of biomedical signal processing, biologis...
