Abstract

The aim of this paper is to propose a new peak detection method for a portable device, which know as modified automatic threshold peak detection (M-ATPD). M-ATPD evolves out of ATPD with a focus on reducing computational time. The proposed method replaces the clustering threshold calculation in ATPD with a standard deviation threshold calculation. M-ATPD reduces computational time by 2 times faster compared to ATPD for control signal and 8.65 times faster compared to ATPD for raw biosignals. Modified ATPD also shows a slight improvement in terms of detection error, with a decrease of about 6.66% to 13.33% in peak detection of noise signals. Modified ATPD successfully fixes the error of peak detection on pulse control signals associated with ATPD. For raw biosignals, in total M-ATPD achieved 19.41% lower detection error compare to ATPD.

Highlights

Amplitude response is most common in electronic application
The results show that modified automatic threshold peak detection (M-ATPD) reduces computational time by 50% compared to ATPD
The results show that the standard deviation threshold calculation reduces time consumption by more than 80% compared to a cluster threshold calculation

Summary

Introduction

Amplitude response is most common in electronic application. Peak detection plays the most important role in analysing amplitude response signals. Noise will cause false peak detection or report a missing peak. This will decrease the accuracy of peak detection. Intelligent peak detection methods are required to increase the accuracy of analysis. Peak detection methods are design for general or specific signal, such as automatic multiscale peak detection (AMPD) [1], the automatic chromatographic peak detection (ACPD) [2], the adaptive threshold method (ATM) [3], the peak of Shannon energy envelope (PSEE) [4] and ATPD [5, 6]
