  4. The Hybrid Equivalent Model 9 ECE-312 , Lec#5 , Nov

    2014 © Ahmad El-Banna • The re model has the advantage that the parameters are defined by the actual operating conditions, • the parameters of the hybrid equivalent circuit are defined in general terms for any operating conditions.     short-circuit forward transfer current ratio parameter short-circuit forward transfer current ratio parameter open-circuit reverse transfer voltage ratio parameter short-circuit input-impedance parameter
