Vrms (Root-Mean-Square Voltage)
The true root- mean- square voltage over the entire waveform.
Where:
x
i
= value at i
th
point.
n = number of points.
Overshoot
Defined as (Vmax-Vtop)/Vamp, useful for square and pulse waveforms. See
Figure 40 on page 102.
Preshoot
Defined as (Vmin-Vbase)/Vamp, useful for square and pulse waveforms.
See Figure 40 on page 102.
