Phase measurement using lissajous patterns
To Measure the phase difference of two sine waves their frequencies must be equal.
1. Connect a 1Volt peak peak, 1KHz sine wave signal from the function generator to the horizontal input of the CRO.
2. Connect the output of phase shift network to the vertical input as shown in figure.
3. Adjust the vertical and horizontal gains properly for good display.
4. Observe Lissajous Patterns for different combinations of R and C values.
