Derivative-Based Peak Detection Algorithm For PPA Waveforms

Peak detection of biological signals is done for identifying the parameters of the respective biosignal for further analysis. In this paper derivative - based peak detection algorithm has been proposed for the detection of peaks of peripheral pulses obtained by Peripheral Pulse Analyser (PPA).PPA has been developed by the Bhabha Atomic Research Centre (BARC), Trombay, Mumbai to check the effect of the peripheral activity of the human body and it generates blood flow patterns. The derivative of a signal is used to detect peak since derivative can be useful for detecting minima and maxima. The proposed algorithm has been compared with the Pan-Tomkins algorithm. A Pan-Tompkins algorithm is used for QRS Detection of ECG signal. The study performed at the Saraswati College of Engineering (SCOE), Kharghar, Mumbai in collaboration with BARC, Mumbai aimed to detect peaks in PPA waveforms.
