# Analog noise budget
# Scope: Independent input-referred RMS voltage noises summed in quadrature.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

sourceNoise = 1 uV
amplifierNoise = 2 uV
resistorNoise = 0.5 uV

total := sqrt(sourceNoise^2+amplifierNoise^2+resistorNoise^2) [uV]

check RMS noise budget: total <= 3 uV

scenario alternative: sourceNoise = 0.8 uV
