“…In the processing of signals in modern measuring equipment, analog-to-digital converters (Analog-to-Digital Converters-ADCs) are widely used [1][2][3] . An actual problem that arises is the linear distortions of the signals caused by the uneven frequency characteristics of the connection channels -amplitude-frequency characteristic (AFC) and phase-frequency characteristic (PFC).…”

A fundamental problem in the transmission of measurement information in contemporary information management systems is the distortion of the signals as an outcome of uneven frequency characteristics of the connection channels. The link channel, as the signal propagation medium, is part of the cascades, as at the transmitter as well at the receiver. The linear distortions of the signal consist in a change in its information parameters, and they can be related to its amplitude and phase spectrum. Compensation of signal distortions is an effective and operative method for increasing the speed of transmitted information and the quality of measurement systems. To compensate for amplitude and phase distortions of the signals, correctors are gained, which are connected coherently to the link channel. The properties of the correctors are identified by their transfer function, frequency response and attenuation. Depending on the assign of elements in the circuit of the corrector, different frequency characteristics and attenuation are derived. Of particular importance is the question of their sensitivity, both to a change in a certain parameter of the scheme, and to the frequency. In the presented work, a fusion of a digital corrector is proponed for the compensation of linear distortions in the transmission of discrete signals. Its characteristics have been explored and analyzed, and conclusions have been drawn regarding its effectiveness and application.
