csúcsértékamplitúdót

csúcsértékamplitúdót, or peak amplitude, is a key concept in electrical engineering and signal processing, referring to the maximum absolute value of a periodic waveform. In alternating current (AC) systems, it represents the highest voltage or current reached within one cycle of a sine wave. For a sinusoidal signal described by v(t) = Vp * sin(ωt), where Vp denotes the peak amplitude, this value indicates the signal’s greatest magnitude. Peak amplitude is vital for assessing the power and energy of a signal, as it directly correlates with the root-mean-square (RMS) value—commonly used for practical measurements. In signal analysis, it aids in evaluating signal strength and distinguishing between waveforms. While peak amplitude clearly defines the signal’s maximum extent, it doesn’t account for the peak’s duration, so it is often paired with other metrics (e.g., peak-to-peak value or RMS amplitude) for comprehensive characterization.
