    The ABCD parameters are defined as
    V1 = AV2 - BI2 .... (i)
    I1 = CV2 - DI2 .... (ii)
    If the output terminal is short-circuited, then
    V2 = 0
    Substituting V2 = 0 into equation (i) and (ii), we get
    V1 = - BI2
    I1 = - DI2
    Input impedance,
    Zin = V1/I1 = B/D
    =12/7 = 1.71 Ω
