Performance comparison of automatic peak detection for portable signal analyser

The aim of this paper is to discuss the automatic threshold peak detection method. An automatic threshold peak detection algorithm is simulated with a control signal in MATLAB to determine ability to detect different signal types. A comparison is made between automatic chromatographic peak detection, adaptive threshold detection, peak of Shannon energy envelop detection, and automatic multiscale peak detection. Based on the experiment results, automatic threshold peak detection can perform peak detection for sinusoidal or triangular signal but not pulse signal. Other algorithms can perform peak detection for pulse signal but not sinusoidal or triangular signal. Automatic threshold peak detection is about 4.47 times faster than peak of Shannon energy envelop and 3980 times faster than automatic multiscale peak detection; however, automatic threshold peak detection is about twice as slow as the adaptive threshold method and automatic chromatographic peak detection.
