Amplitude#Peak-to-peak amplitude

The peak -to-peak value, referred 5483-1:1983 ( " Time-dependent variables ") as the peak-to- valley value according to the current standards in DIN, in electrical engineering indicates the amount of deflection from the lowest value to the highest value of a periodic process. For symmetric alternating quantities, the peak- to-peak value equal to twice the maximum value.

The peak -to-peak voltage can be measured with the oscilloscope. The peak -to-peak value of an AC voltage is the sum of the maximum voltage of the positive half cycle and the amount of the minimum voltage of the negative half cycle. It is expected here " from tip to tip ", even if present in the extremes, not peak.

The indication of the voltage of a signal must be included to what size it is. In DIN 40110-1 ( " AC quantities " ) to distinguish the example of a voltage

• The instantaneous value u (t),
• The maximum value ( in any desired periodic voltage), the ( a sinusoidal alternating current) peak value û (with any alternating voltage ), or the amplitude or U.S.,
• The peak- to-peak or Uss,
• The rms value of U or U eff.

The European mains voltage at the consumer level is specified as rms Vrms = 230 V. She has a peak -to-peak value of Vpp = 650 V and a peak value of Us = 325 V.
