The H21 parameter represents the short circuit current gain in a two-port network, while the G21 parameter represents the open circuit voltage ratio. This calculator converts between these parameter representations using the delta impedance of G.
The calculator uses the formula:
Where:
Explanation: The formula converts G-parameters to H-parameters by considering the relationship between open circuit voltage ratio and short circuit current gain through the delta impedance.
Details: Accurate conversion between parameter representations is crucial for circuit analysis, network theory applications, and designing electronic systems with different parameter requirements.
Tips: Enter the G21 parameter value and Delta-G value. Both values must be valid numerical values, and Delta-G cannot be zero (division by zero is undefined).
Q1: What is the physical significance of H21 parameter?
A: H21 parameter represents the short-circuit current gain, indicating how much current flows through the output when the input is short-circuited.
Q2: What does Delta-G represent in this context?
A: Delta-G is the determinant of the G-parameter matrix, representing the delta impedance of the G-parameter system.
Q3: When should this conversion be used?
A: This conversion is useful when you have G-parameters but need H-parameters for your circuit analysis or design requirements.
Q4: Are there limitations to this conversion?
A: The conversion assumes linear network behavior and may not be accurate for non-linear systems or at very high frequencies.
Q5: Can this be used for all types of networks?
A: This conversion is valid for linear, time-invariant two-port networks that can be described using G and H parameters.
