How To Admittance smith chart: 7 Strategies That Work

Admittance of an AC circuit is the reciprocal of its impedance. Using the impedance value one can easily derive the Admittance values of the circuit. Admittance ‘Y’ can be measured as Y = 1/Z. where ‘Z’ is the impedance, Z = R+jX. So, admittance ‘Y’ can be written as, Y = 1/R+jX. Thus, the formula of Admittance when derived from ...Admittance values calculated from the S-parameters were plotted on the admittance Smith chart, and the equivalent circuits with four parallel sub-circuits were synthesized by curve fitting. ...admittance (blue) mapping.
