2-12 Construction of a Lissajous figure. In Fig. 2-12 we show the construction that
one can make ifco2 = 2co!and S = ir/4. We have chosen to divide the reference
circle for the motion of frequency o>2 into eight equal time intervals, i.e., into arcs
...

1.13 is known as Lissajous figure. These figures prove useful in interpreting
oscillograph records, which may depict the actual motion of a point on a vibrating
structure or a machine, for example, a shaft undergoing whirl due to unbalance ...

The Physics of Waves and Oscillations
The beam falls on a fluorescent screen on which the Lissajous figure
corresponding to the resultant motion can be seen. If the frequencies of the
electrical oscillations are not exactly in a simple ratio, the figure will be seen to
change its form ...

wound around the cylinder onto the x,, x2 plane gives the desired orbit, called a
Lissajous figure. Lissajous figures can conveniently be seen on an oscilloscope
which displays independent harmonic oscillations on the horizontal and vertical ...
When the parametric equations of a point describe simple harmonic motion, the
resulting curve is called a Lissajous figure. When voltages of different
frequencies are applied to the vertical and horizontal plates of an oscilloscope, a
Lissajous ...

Understanding Pendulums: A Brief Introduction
A consistent definition of the phase, , of a Lissajous figure can be obtained by
definition of for two extreme cases as follows. A Lissajous figure is in phase ( D 0ı
) when cusps appear, and this is sometimes called the cusped phase, for
example ...

When a particle has superimposed upon it two mutually perpendicular simple
harmonic motions simultaneously, the resultant path of the particle is known as a
Lissajous figure. 3. When two simple harmonic vibrations of equal time periods
act ...

ELECTRONIC INSTRUMENTATION, 3E
If one frequency is an integral multiple (harmonic) of the other, the pattern will be
stationary, and is called a Lissajous figure. In this method of measurement a
standard frequency is applied to one set of deflection plates of the CRT tube
while ...

The frequency of this oscillator is varied until a single-looped or two-looped or
three-looped or complex Lissajous figure is obtained. In case the single-loop
stationary pattern is obtained, the frequency of the sinusoidal voltage is the same
as ...

In order to show that the output signal from B-coils does not dependent on the
exciting voltage wave form, we show the Lissajous figure of the exciting voltage

Lissajous figure is the parabola (a/b = 2, δ = π/2). Other ratios produce more complicated curves, which are closed only if a/b is rational. «Crikey, 一月 08»
