ABSTRACT
Acquisition and reliable parameter extraction of human bio-signals is extremely sensitive to interferences. Analogue filters have been used in the past to remove artefacts but they only help to suppress these contaminations and are difficult to realize. Their simulated computer based digital equivalents are however a viable and effective solution to this. But these filters are mostly tested on stored database and so there is a need to develop a system where real time acquired human signal is filtered and analyzed online on a computer. Present paper deals with design and simulation of digital techniques like FIR filter, IIR notch filter, spectrum analysis and convolution implemented on real time, non-invasively acquired carotid pulse wave on a computer based environment named Simulink using FDA tool. Results obtained show the accuracy of the designed techniques and gives an easy model to online acquire and filter bio-signals sitting at home.
