Proposed method depicted as a MISO system. (Left) Polynomial FIR filter bank for modeling the transfer function between respiratory effort belt and spirometer signals. (Right) A simplified structure for piezo-based and inductive-based respiratory effort belts. Here, FIR₁ and FIR₂ represent the filters FIR₁₂ and FIR₂₂ on the left, respectively.
