For Matching Two Impedances where Z_{1} > Z_{2} | Matched, use a resistor ,
R_{L} in series with
the smaller impedance such that |

If the smaller impedance
only is to be matched, use a resistor R_{S} in shunt across the larger impedance such that |

Where Only One Impedance is to be Matched | |||
If the larger impedance only is to be | Here also |
