Question
The Smith chart is normalized with respect to the reference value of this quantity. For 10 points each:
[10m] Name this quantity whose “matching” is visualized on Smith charts. This quantity equals electrical resistance plus reactance times the imaginary unit, j.
ANSWER: electrical impedance [or source impedance or reference impedance or characteristic impedance]
[10e] In the Smith chart, the paths between points of equal resistance have this shape. A connected portion of the circumference of a circle has this shape.
ANSWER: circular arc [or the arc of a circle]
[10h] The distance from the center of the Smith chart equals the magnitude of this quantity. This quantity, which measures an interruption to transmission, equals the difference between load and reference impedances over their sum.
ANSWER: reflection coefficient [prompt on uppercase gamma; prompt on answers describing amount of reflection]
