SIGNAL PROCESSING DEVICE Russian patent published in 2002 - IPC

FIELD: signal processing technology. SUBSTANCE: device has frequency filter, digitizer, and unit for reduction to perfect device. As an alternative device may also have noise suppression unit, interpolator, input signal element parameter qualifier, and signal description synthesizer; noise suppression unit may have signal rate-of-rise estimating unit, normalizing unit; input signal parameter qualifier may incorporate switch, next signal element parameter qualifier, shaper of frequency filter output response to signal element, storage subtracter, synthesis completion decision circuit. EFFECT: enhanced resolution of signal elements and sensitivity to its low-contrast elements; enhanced speed, simplified design. 6 cl, 12 dwg
