WebFeb 18, 2024 · The distance from peak to peak, that is, the separation between pulses, depends on the repetition rate since it is the periodicity of the pulse. We calculate it with: \Delta T = \frac {1} {f} ΔT = f 1 The pulse energy depends on the average power of the pulse: E_ {\text {pulse}} = \frac {P_ {\text {avg}}} {f} E pulse = f P avg 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.
