Abstract: A signal processing apparatus (100) comprising a noise detector (102) configured to: receive a stream of information representative of a stream of audio signal samples (112); and detect samples in the received stream of information (112) that are distorted by impulse noise in order to generate a noise detection signal (114), wherein the noise detection signal (114) also identifies preceding and succeeding samples that are undistorted. The signal processing apparatus (100) also comprises a processor (104) configured to replace distorted samples in the received stream of information with composite predicted values (426; 526) to provide a reconstructed stream of audio signal samples (116).

Abstract: The invention relates to a method of controlling a display screen, particularly a foil display built up of a number of lines, the display screen comprising at least one light source, a movable element, and selection means for locally bringing the movable element into contact with the light source, in which the selection means comprise row and column electrodes and means for applying control voltage signals to the invention also relates to a display source, a movable element, and selection means for locally bringing the movable element into contact with the light source, in which the selection means comprise row and column electrodes and means for applying control voltage signals to the row and column electrodes. Because of a minimum switching time of pixels, not all pixels, i.e. lines can be activated immediately when the display screen is addressed line by line.

Abstract: The display device (1) comprises picture elements (5) arranged in substantially parallel lines (6) on a display panel (2), and selection means (3) for controlling the decoupling of light from an optical waveguide plate at the picture elements. The selection means (3) are arranged for multiline addressing of the picture elements (5). For displaying gray scales, image information (4) is decomposed into a number of subfields (13) which are displayed. The time efficiency of the addressing of picture elements (5) in lines (16) in the subfields (13) is increased, enabling the display device (1) to display a relative large number of gray method of operating a display device (1) is carried out when the device is in operation.
