Sorry for the wrong substitution at 15:05 to 15:30. Kindly consider C=b/(2*pi*f*Z0) as correct substitution.

Very good explanation! One of the few that is based on just the impedance chart, which seem to be what most students are learning on.

Sir i wanna ask, if the impedance normalization is on outside r=1 , for example 1-0.2 j , is the jx that - 0.2j , and after that we paralel it with the jb ? (Admintace) Thank you sir

Sir what if normalized zl is 2-2j which is outside the 1+jx circle do we map it the opposite point on the 1+jx circle or we follow 2-2j till it reaches the point in 1+jb circle ?
@RFDesignbasics
@RFDesignbasics 5 жыл бұрын
2-2j is not outside 1+jx circle. It's inside 1+jx circle So follow the first circuit. Refer starting of this video.

@RFDesignbasics 5 жыл бұрын
We should normalise zl not z0. In case the normalised load is on 1+jx circle than you need either capacitor or inductor to match it. You don't need LC combination.

Adding 0.48 and 0.4 will give 0.88 , so the value of b =0.88 is correct
