To evaluate the frequency and characteristics of square wave jerks (SWJs) in normal subjects. These have been well documented to occur as isolated movements in normal subjects as often as 16/minute. The square wave is a special case of a pulse wave which allows arbitrary durations at minimum and maximum amplitudes. The square wave differs from the sine wave in that, besides the fundamental frequency, it also contains odd harmonics.The sum of these harmonics and the fundamental give it its square shape. Read any comments already posted on the article prior to submission. As already mentioned, an ideal square wave has instantaneous transitions between the high and low levels. Sound generation of this sort presents a very practical problem, however, because it takes a great amount of time to specify all the components of a waveform. -Surface swell in a pond, here is the surface tension of the water that exerts as a restoring force. In an ideal square wave, the transitions between minimum and maximum are instantaneous. A square wave is a non-sinusoidal periodic waveform in which the amplitude alternates at a steady frequency between fixed minimum and maximum values, with the same duration at minimum and maximum. Additionally, the distortion effect used on electric guitars clips the outermost regions of the waveform, causing it to increasingly resemble a square wave as more distortion is applied.
