Digital potentiometers in the tasks of settings precision analog RC-filters taking into account the tolerances for passive components

摘要

The application features of digital potentiometers as controlled elements for the tasks of setting active RC-filters in the structure of communication systems analog interface and automatic control are considered. The research paper is based on a selected method of parameters for setting circuits with digital potentiometers providing necessary precision and setting ranges. The sections contain examples oriented for application of setting circuits of active RC-filters with digital potentiometers.
