Question 3: In a Smith chart, what does a point on the outermost circle represent?

Which action should you take?

Choose only one option

Purely resistive impedance

Maximum reactance

Infinite impedance

Zero impedance

Question 4: In RF signal transmission, what is the effect of signal attenuation over distance?

Which action should you take?

Choose only one option

Signal strength remains constant regardless of distance

Signal strength decreases with distance, reducing transmission quality

Signal strength increases with distance, causing saturation

Signal strength fluctuates randomly
