When two two-port networks are connected in parallel at both ports, which parameter matrices are especially convenient to add directly?

  • Az-parameters
  • By-parameters
  • CABCD parameters
  • Dh-parameters only
Report an error
Correct Answer: B. y-parameters
Explanation: For parallel-connected two-ports, corresponding port voltages are common and currents add, making admittance or y-parameters convenient.
Reference: Standard network theory: parallel two-port connection
