Which of the following is a common use for a Smith chart?
Determine the length and position of an impedance matching stub✓Respuesta correcta
Determine the impedance of a transmission line, given the physical dimensions
Determine the gain of an antenna given the physical and electrical parameters
Determine the loss/100 feet of a transmission line, given the velocity factor and conductor materials
Explicación
Adding a matching stub means finding where along the line the impedance has the right resistive part and then choosing a stub whose reactance cancels what remains. Both steps — distance from the load and stub length — are read directly off the chart as fractions of a wavelength.
