1. What is H11 Parameter?

H11 Parameter is the short circuit input impedance in two-port network analysis. It represents the input impedance when the output port is short-circuited.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( H11 \) — Short circuit input impedance (Ohm)
• \( Y11 \) — Driving point admittance at port 1 (Siemens)

Explanation: The H11 parameter is simply the reciprocal of the Y11 parameter, converting admittance to impedance.

3. Importance of H11 Parameter Calculation

Details: Accurate calculation of H11 parameter is crucial for analyzing two-port networks, designing electronic circuits, and understanding impedance matching in communication systems.

4. Using the Calculator

Tips: Enter Y11 parameter value in Siemens. The value must be valid (Y11 > 0).
