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

Sum of the ABCD matrices representing the individual two ports

Product of ABCD matrices representing the individual two ports

Difference of the ABCD matrices representing the individual two ports

Sum of transpose of ABCD matrices representing the individual two ports

Correct Answer : Option (B) : Product of ABCD matrices representing the individual two ports

Explanation : When two networks are connected in cascade, each of the two networks are represented as a 2×2 square matrix. Then to obtain the equivalent matrix of the cascade, the product of the ABCD matrices of each stage is taken.
