Peak-to-Peak Voltage Formula
Vpeak = Vrms sqrt(2)
Vpp = 2 Vpeak
Peak-to-peak voltage is the distance from the lowest point to the highest point of a waveform. For a sine wave, it is twice the peak voltage.
⚠ These conversions assume a pure sine wave. Square waves, triangle waves, and pulses have different RMS relationships.
What Is Peak-to-Peak Voltage?
Peak-to-peak voltage describes total waveform swing from minimum to maximum. It is common in oscilloscope readings and signal specifications.
Total Swing
Vpp measures full high-to-low voltage span.
RMS Link
For sine waves, RMS converts through sqrt(2).
Oscilloscope Use
Scopes commonly display Vpp directly.
Waveform Specific
The formula depends on waveform shape.
Example: For Vrms = 7.071 V, Vpeak = 10 V and Vpp = 20 V.
Applications of Peak-to-Peak Voltage
Oscilloscopes
Signal Testing
Audio Electronics
