For a simple admittance Y, the ABCD parameters are:

Electronics and Communication Engineering (ECE) : Microwave Communication - Quiz(MCQ)

A=1, B=0, C=Y, D=1

A=1, B=0, C=Z, D=1

A=1, Y=B, C=0, D=1

A=Z, B=1, C=1, D=0

Correct Answer : Option (A) : A=1, B=0, C=Y, D=1

Explanation : If simple admittance or an equivalent admittance of a network is represented as a ABCD matrix, writing the equations in terms of voltage and current and setting each variable to zero, the four constants are obtained. For an admittance Y, the constants are A=1, Z=B, C=0, D=1.
