Abstract

Present invention relates to a method and a device (145) for improving the signal-to-noise ratio (S/N) in a system (40) for measuring flatness of a strip (1) of rolled material, comprising a measuring roll (2) having a number of said measuring devices (22) for force/pressure registration. Said devices (22) generate measurement output signals Upi depending on the contact between the strip and the measuring roll. The invented device (145) determines and generates time slots having a determined time length, synchronises said time slots to the appearance of force components on an input of at least one quantity processor (62) of said signal processors (60) and controls at least one of said quantity processors (62) to be open for registration of an incoming force component signal during said time slot and to be closed until the next successive time slot appears. The present invention also provides a computer program product and a flatness determination signal for accomplishing said objects of the invention.
