# Passive RC/RL filter
# Scope: Ideal unloaded RC low-pass at one sinusoidal frequency.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

resistance = 1000 ohm
capacitance = 100 nF
frequency = 1000 Hz

corner := 1/(2*pi*resistance*capacitance) [Hz]
magnitude := 1/sqrt(1+(frequency/corner)^2)

check passband gain target: magnitude >= 0.7

scenario alternative: resistance = 800 ohm
