Direct processing circuit for unifying the processing of analog and digital signals in control and monitoring circuits, particularly in AC electric drives

摘要

A direct processing circuit for unifying the processing of analog and digital signals in control and monitoring circuits, particularly in AC electric drives, comprising means for integrating logic and digital functions. Said means are connected to a digital processor and are adapted to send digital signals to means for multiplying digital/analog signals. The multiplying means receive in input analog signals which are meant to be multiplied with the digital signals in order to obtain analog output signals as a function of preset numeric data. The means for integrating logic and digital functions drive the multiplying means in time-sharing mode.
