摘要

FOR THE ACQUISITION SYSTEM AND DATA ANALYSIS IN TESTS Subjective assessment of, for example, television images, comprising an electronic circuit connected to the computer Cy CONNECTOR FORMED BY Potentiometers R1 and R2 and resistors R3 and R4 GROUND, BESIDES a button SW1 THAT IS POWERED BY THE OBSERVER AND BY LED diode D1 sHAPING from the computer. The user moves Potentiometers UP LEVEL INDICATOR BETWEEN PESIMO PUNCTUATION AND EXCELLENT and actuates the enabling switch. COMPUTER DIGITALLY SENT HOME TENSION potentiometers, TURNING sample obtained Potentiometers VALUES DIGITAL that are read BY THE COMPUTER BY PROCEDURE SUCCESSIVE APPROACHES WITH CORRECTION nonlinearity Potentiometers, CONFIRMATION OF MEASURE, and taking corrective measures ERROR. REVIEWS SUBJECTIVE APPLICATION IN SAMPLES, SUCH AS TV images.
