Lissajous Patterns
Lissajous Patterns - 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.

With the help of the 3d ray tracing model, all theoretical patterns can be seen to agree very well with the experimental patterns; An accurately calibrated standard variable frequency source is used to. Web lissajous figures are figures that are turned out on the face of an oscilloscope when sinusoidal signals with different amplitudes and different phases are applied to the time base (real axis) and deflection plate (imaginary axis) of the scope. Web the simplest lissajous patterns appear in the oscilloscope display when the frequencies of the signals are the same, i.e.. A straight line indicates a 0º or 180º phase difference. These patterns will vary based on the amplitudes, frequencies and phase differences of the sinusoidal signals, which are applied to both horizontal & vertical deflection plates of cro.

(4) they are sometimes known as bowditch curves after nathaniel bowditch, who studied them in 1815. He would use sounds of different frequencies to vibrate a mirror. Web this video provides a technical introduction to the creation, interpretation, and use of lissajous patterns. Graph functions, plot points, visualize algebraic equations, add sliders, animate graphs, and more. In general, whenever a measured waveform needs to be compared with some reference, either in terms of phase or frequency (or both), a lissajous curve is a very useful way to visualize this comparative measurement. Plug one wave generator into each input of a dual trace. The signal, whose frequency is to be measured, is applied to the y plates. \displaystyle {x}= {a}\ \sin { {\left ( {a} {t}+\delta\right)}} x = a sin(at+ δ) \displaystyle {y}= {b}\ \sin { {\left ( {b} {t}+\gamma\right)}} y = b sin(bt+ γ) continues below ⇩.Using a scope to display Lissajous patterns Electrical Engineering
