SHAPER OF INFORMATION QUANTIZATION PULSES OF SCREEN OF CATHODE-RAY TUBE Russian patent published in 1995 - IPC

FIELD: computer engineering. SUBSTANCE: device has unit 1 which serves for generation of pulses which correspond to position of electronic beam on the cathode-ray tube screen. In addition device has video signal generation unit 2, row parity detection unit 3, pulse delay unit 4, commutator 5. This results in possibility to increase resolution. By this reason number of complex multiplication which are needed for two-dimension algorithms of quick Fourier transform are decreased by 25 percents. EFFECT: simplified generation and processing of two-dimensional images. 3 cl, 3 dwg
