On oscilloscope screen for dynamic measurement, lissajous diagram is normally used to determine the ______________ of the input signal?
Correct answer: A. Frequency
- A. Frequency
- B. Amplitude
- C. Damping
- D. None of these
Explanation
A Lissajous figure compares an unknown periodic signal with a reference signal, allowing the frequency ratio to be found from the plotted pattern. With a known reference frequency, the input frequency can therefore be determined.
