- Two derivation processes for relationships between the decoupled and coupled transfer functions are presented.
- Issues related to immeasurability of coupled transfer functions are addressed.
- The proposed method is validated by numerical and experimental case studies.

A generalized method for predicting the decoupled transfer functions based on in-situ transfer functions is proposed. The method allows predicting the decoupled transfer functions using coupled transfer functions, without disassembling the system. Two ways to derive relationships between the decoupled and coupled transfer functions are presented. Issues related to immeasurability of coupled transfer functions are also discussed. The proposed method is validated by numerical and experimental case studies.
