This device consists of a rotating cylinder covered with a vertical sine wave grating presented in virtual three - dimensional (3 - D) space on four computer monitors arranged in a square.
Briefly, a rotating cylinder covered with a vertical sine - wave grating was calculated and drawn in virtual 3 - dimensional space on 4 computer monitors facing to form a square.
Distortion means the sound waves contain more energy: the sound wave looks like a square rather than a sine, so RMS is more than 70 % of peak power.
The Flaunt e-bikes are also said to have a couple of other features that help them rise above their competitors, including the geared hub, which could make for more optimal operation on hills, a «walk mode» which is a pedal - free 5 mph assist for pushing the bike, a brake sensor that cuts off the electric motor when slowing for corners, and a sine wave controller that is said to offer a smoother motor cut - in than square wave models (which can be abrupt).
