A technique for real-time correction of measurement instrument transducers frequency responses

As it is well known, transducers are the most important components of a measurement system: they converts the physical quantity, which has to be measured, in an electrical one, processed in turns by electronic instruments. It is also known that they are the major source of uncertainty, which it is desirable to be as low as possible; obviously, their costs grow, sometimes exponentially, with their performances. Since digital measurement equipments, based on data acquisition systems and digital processors, represent nowadays the core of most electronic measuring instrument, it is possible to use them in order to compensate errors coming from transducers, without increasing their costs. So in this paper a digital technique for the correction of transducers errors is presented: it has got a low computational burden, and therefore it can be implemented in real-time even on low cost digital processors.
