• Q7
If Z- parameter is given as Z11 = 6, Z12 = 3, Z21 = 10, Z22= 5 find y- parameter.
Z11 = 5, Z12 = 3, Z21 = 10, Z22= 6
Z11 = -6, Z12 = 10, Z21 =3, Z22= -5
cannot be defined.
Z11 = 5, Z12 = -3, Z21 = -10, Z22= 6

• Q8
find the y- parameter of the circuit given
y12= y22= z1 +2 z2 and y21=y11= z1
y11= y22= z1 +2 z2 and y21=y12= z1
y12= y22= z1 and y21=y11= z1 +2 z2
y11= y22= 1/z1 +1/(2 z2) and y21=y12= 1/z1
