Before revision: In that circumstance, for n identical first-order sections in cascade, the voltage transfer function of the complete network is given by; consequently, the total roll-off is given by, A similar effect can be achieved in the digital domain by repeatedly applying the same filtering algorithm to the signal.Todd, pp107-108 500px|LC low-pass ladder circuit.
