One of the quickest methods of determining frequency is by using Lissajous patterns produced on a screen. … This particular pattern results when sine waves are applied simultaneously to both pairs of the deflection plates.
: any of an infinite variety of curves formed by combining two mutually perpendicular simple harmonic motions, commonly exhibited by the oscilloscope, and used in studying frequency, amplitude, and phase relations of harmonic variables.

Also, What are Lissajous figures used for?
Introduction. When using an oscilloscope, we can plot one sinusoidal signal along the x-axis against another sinusoidal signal along the y-axis. The result is a Lissajous figure. Lissajous figures tells us about the phase difference between the two signals and the ratio of their frequencies.
Why the Lissajous figure is very useful?
A Lissajous curve is used in experimental tests to determine if a device may be properly categorized as a memristor. It is also used to compare two different electrical signals: a known reference signal and a signal to be tested.

What is meant by Lissajous pattern?
Lissajous figure, also called Bowditch Curve, pattern produced by the intersection of two sinusoidal curves the axes of which are at right angles to each other. … Lissajous used a narrow stream of sand pouring from the base of a compound pendulum to produce the curves.
How do you find the Lissajous pattern?
When the phase shift is 45°, the Lissajous pattern is an ellipse whose centerline slopes upward from left to right. When the phase shift in 180°, the Lissajous pattern is a straight line sloping down from left to right.
How lissajous patterns are displayed?
A Lissajous figure is displayed on the screen when sinusoidal signals are applied to both horizontal & vertical deflection plates of CRO. … If the Lissajous figure is a straight line with an inclination of 135∘ with positive x-axis, then the phase difference between the two sinusoidal signals will be 180∘.
How do you make Lissajous figures on an oscilloscope?
What are measurements from a Lissajous figure?
The Lissajous pattern indicates the phase difference by the shape of the X-Y plot. A straight line indicates a 0º or 180º phase difference. The angle of the line depends on the difference in amplitude between the two signals, a line at 45º to the horizontal means the amplitudes are equal.
What is the use of Lissajous figure?
Introduction. When using an oscilloscope, we can plot one sinusoidal signal along the x-axis against another sinusoidal signal along the y-axis. The result is a Lissajous figure. Lissajous figures tells us about the phase difference between the two signals and the ratio of their frequencies.
What is Lissajous pattern in CRO?
Lissajous figure is the pattern which is displayed on the screen, when sinusoidal signals are applied to both horizontal & vertical deflection plates of CRO. … The above Lissajous figure is in elliptical shape and its major axis has some inclination angle with positive x-axis.
What is the use of Lissajous pattern?
A Lissajous curve is used in experimental tests to determine if a device may be properly categorized as a memristor. It is also used to compare two different electrical signals: a known reference signal and a signal to be tested.
What is the relation for frequency determination in lissajous method?
To determine the frequency from any Lissajous figure, count the number of horizontal loops in the pattern, divide it by the number of vertical loops and multiply this quantity by fh (known or standard frequency). In Fig. 7.31 (g), there is one horizontal loop and 3 vertical loops, giving a fraction of 1/3.
