# Signal RMS, average and crest factor
# Scope: RMS of three supplied equal-duration signal samples.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

a = 1 V
b = -1 V
c = 0 V

mean := (a+b+c)/3 [V]
rms := sqrt((a^2+b^2+c^2)/3) [V]

check RMS voltage budget: rms <= 1 V

scenario alternative: a = 0.8 V
