Smith Chart Example (Continued)
Input admittance yL for the line:
- Draw a line from zin through the center of the Smith Chart.
- 180o opposite zL locate yL which is the intersection of this line with the constant rL circle.
- Read the normalized admittance yin.
Answer: yin1=0.42-j0.12
NOTE: Actual input admittance is Yin=(yin)(Yc)=(0.42-j0.12)(1/50)=0.0084-j0.0024 (Siemens)
