A room which has totally sound absorbent walls, so that no reflected waves can exist and only the direct waves are heard.

The process whereby a material is magnetised by applying a unidirectional field upon which is superimposed an alternating field of gradually decreasing amplitude. One form of this process is analogous to the recoding process using AC Bias.

Animation is the process of fooling the human eye into perceiving a moving object by presenting the eye with a rapid succession of still pictures. Each still is called a frame. On the Cubicomp, animation consists of moving objects which, in themselves, stay unchanged.

The motion of an object as it flies through space is called its animation or motion path.
Industry:Entertainment
Directional dependence of magnetic properties, leading to the existence of easy or preferred directions of magnetization. Anisotropy of a particle may be related to its shape, to its crystalline structure, or to the existence of strains within it. Shape anisotropy is the dominant form in acicular particles.

A philtre (typically a lowpass filter) used to bandwidthlimit the signal to less than half the sampling rate before sampling.

Computer-generated fonts that have been digitally rounded for smooth edges.

The process of reducing aliasing effects. Aliasing occurs because a raster system is “discrete,” i.e., made up of pixels that have finite size. Representing a line with black and white pixels results in “jaggies,” or “aliases.” These are particularly disturbing during animation. To correct them, “anti-aliasing” techniques are used. These tech AM-VSB (Amplitude Modulation with Vestigial Sideband) – The form of modulation used in broadcast and cable television transmission. It is more efficient than dual-sideband amplitude modulation and is easier to implement than single-sideband amplitude modulation.

A complex technique of preventing picture highlights from “comet-tailing” due to lack of beam current in the camera tube.
(The usually coloured trail behind a moving, very bright light/reflection in a picture is called a “comet-tail” since the effect looks similar to an astronomical comet.) The technique involves a special tube and circuitry to drive it. Basically, the charge due to a very bright object is never allowed to build up to an unmanageable level by discharging the target above a preset level during horizontal retrace time when the ACT action is turned on, with an increased beam current.

A) An adjustable opening in a lens which, like the iris in the human eye, controls the amount of light entering a camera. The size of the aperture is controlled by the iris adjustment and is measured in f-stops. A smaller f-stop number corresponds to a larger opening that passes more light.
b) As applied to ATV, the finite size and shape of the point of the electron beam in a camera or picture tube. As the beam does not come to an infinitesimal point, it affects the area around it, reducing resolution.
