Question

Which of the points below correctly complete(s) the given statement?

The Lissajous patterns help in the measurement of

1. Phase difference between two sine waves only

2. Frequency of one waveform only, if the frequency of other waveform is known

1. Neither 1 nor 2
2. Both 1 and 2
3. Only 1
4. Only 2

Answer 1

Correct Answer - Option 2 : Both 1 and 2

Using Lissajous patterns we can measure both phase difference and frequency. We can measure the phase difference between two sine waves. If we know frequency of one wave form, we can measure the frequency of second wave form.
