WebMeasuring Amplitudes of Peaks. This example shows peak analysis in an ECG (Electro-cardiogram) signal. ECG is a measure of electrical activity of the heart over time. The signal is measured by electrodes attached to the skin and is sensitive to disturbances such as power source interference and noises due to movement artifacts. WebJul 9, 2014 · It uses a sliding window and counts how many times a local peak appears as a maximum as window shifts along the x-axis. As @DrV suggested, no universal definition of "local maximum" exists, meaning that some tuning parameters are unavoidable. This function uses "window size" and "frequency" to fine tune the outcome. tawanrath fah
