What
’
s the difference of amplitude in Vpp and the corresponding value in
Vrms?
Answer:
Vpp is the unit for signal peak-peak value and Vrms is the unit for signal effective value.
The default unit is Vpp.
Note
：
For different waveforms, the relation between Vpp and Vrms is different. The
relation of the two units is as shown in the figure below (take sine waveform as
an example).
According to the figure above, the conversion relation between Vpp and Vrms
fulfills the following equation:
Vpp = 2
2
Vrms
For example, if the current amplitude is 5Vpp, For sine waveform, the
converted value is 1.768Vrms.
