DIGITAL SIGNAL PROCESSING IN BIOMEDICAL ENGINEERING

DIGITAL SIGNAL PROCESSING IN BIOMEDICAL ENGINEERING                                      

ABSTRACT

Digital Signal Processing, a field which has its root in the 17th & 18th century mathematics has become an important modern tool in a multitude diverse field of science & technology. The techniques & applications of this field are as old as Newton & Gauss & as new as digital computers & integrated circuits.
digital Signal Processing means processing signals in digital domain, which includes
# Modifying signal characteristics
# Multiplying two signals ( Modulation, Correlation)
# Filtering
# Averaging
DSP can extract one signal from another. The purpose of such processing may be to estimate characteristic parameter of a signal into a form which is in some sense more desirable. DSP can analyze ECG or EEG to extract some characteristic parameter.
