Web7 apr. 2024 · The node quality factor can also be obtained from the admittance of the node. If the equivalent admittance of a node is Y = G + jB, we have: \[Q_n=\frac{ B }{G}\] Equation 3. At each node of the L-type matching network, we can use either Equation 1 or 2 to find the quality factor of that node (both equations produce the same value).

WebSusceptance. In electrical engineering, susceptance ( B) is the imaginary part of admittance ( Y = G + jB ), where the real part is conductance ( G ). The reciprocal of admittance is impedance ( Z = R + jX ), where the imaginary part is reactance ( X) and the real part is resistance ( R ). In SI units, susceptance is measured in siemens (S). WebThe formula for converting from rectangular representation of a complex number (a + jb) to polar representation computes the radius r as r = sqrt (a^2 + b^2).
