Concept:

ABCD Parameter:

We know that the ABCD parameter of the transmission line

A = D

AD – BC = 1

= 

So, B = 8

Conditions of reciprocity and symmetry in terms of different two-port parameters are:

Parameter

Conditions of reciprocity

 Conditions of symmetry

Z

z12 = z21

z11 = z22

Y

y12 = y21

y11 = y22

T(ABCD)

(AD – BC) = 1

A = D

h

h12 = -h21

(h11h22 – h12h21)

= 1
