# Signal-to-noise ratio and dynamic range
# Scope: RMS voltage signal-to-noise ratio with identical impedance.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

signal = 1 V
noise = 0.001 V

ratio := signal/noise
snrDb := 20*log10(ratio)

check SNR target in dB: snrDb >= 50

scenario alternative: signal = 0.8 V
