A system for reproducing stereographic images is provided that includes a display unit that has a pixel array for representing image data which reproduces the same when controlled with stereoscopic image data, and a light source for fully illuminating the pixel array. The system further includes a pair of glasses that are suitable to make the reproduced stereoscopic image data available to a wearer of the pair of glasses in an eye-selective manner. The display unit has at least one additional light source for fully illuminating the pixel array. Every light source is additionally configured to emit light in a plurality of narrow spectral ranges, thereby defining a color range, the spectral ranges of the light sources being orthogonal to each other. The system also includes a control unit that sequentially operates the light sources. The pair of glasses has optical glasses, spectral transmission ranges of which are orthogonal to each other and correspond to the spectral ranges of the light sources in such a manner as to allow the reproduction of stereographic images in a reliable and cost-effective manner.

A method for compensating for multipath effects when receiving a vestigial sideband modulated TV signal, one portion of the spectrum of the undistorted TV signal being symmetrical with respect to a video carrier frequency, and deviations from the symmetry of the relevant portion of the spectrum that exists in the undistorted state being analyzed in order to suppress the multipath effects.

Suppression of multipath effects in the transmission of analog TV signals

A method for analog-to-digital conversion of an analog signal includes decomposing the signal in the time domain into intervals, and transforming these intervals one after another using orthogonal functions, the coefficients corresponding to the orthogonal functions being defined and digitized. The transformed signal is then inversely transformed in the digital domain using the digitized coefficients and the same or different orthogonal functions. A high level of performance with respect to bandwidth and resolution may be achieved.

Method and device for analog-to-digital conversion of a signal

A method for digital-to-analog conversion of a digital signal (x (t )) comprises resolving the signal (x (t )) in the time region into intervals and successively transforming these intervals on the basis of orthogonal functions (g (t)). Coefficients (a ) associated with the orthogonal functions (g (t)) are determined and converted from digital to analog and the signal (x (t)) is transformed back in the analog region on the basis of analog coefficients (a ), which result therefrom, by means of orthogonal functions (h (t)).
