سؤال 568

Which of the following is often determined using a Smith chart?

  1. Beam headings and radiation patterns
  2. Satellite azimuth and elevation bearings
  3. Impedance and SWR values in transmission linesپاسخ درست
  4. Point-to-point propagation reliability as a function of frequency

توضیح

Because a Smith chart shows normalized impedance and the magnitude of Γ at the same time, both the impedance at any point on a line and the resulting SWR can be read off it directly. Beam headings, satellite bearings, and propagation reliability come from entirely different tools.
