FIELD: information technology.
SUBSTANCE: present invention relates to a method for digital signal processing (DSP) and devices to this end. Signal processing system comprises a touch sensor comprising a connecting line in a matrix configuration, a transmitter and a receiver. Signal processing method comprises transmitting a selected signal from a transmitter signal to a touch sensor, wherein transmission additionally comprises touch sensor excitation with transmitted signal on two edges of matrix, reception by receiver connected to touch sensor, selected and transmitted signal, determining expected conversion of transmitted signal as a function of selected distance between transmitter and receiver, generation of expected correlation signal based on certain conversion, and compensation of at least part of expected conversion of transmitted signal using expected correlation signal received at touch sensor.
EFFECT: technical result of disclosed group of inventions is high signal-to-noise ratio (SNR) of touch sensors.
