A recursive fir technique applied to the efficient tracking of resonant sensor systems

Conference item

A new technique called Prism signal processing has been developed which offers an FIR response, including a linear phase characteristic, while being a fully recursive calculation. The Prism signal processing block accepts a time series input and generate either one output or two orthogonal outputs, where the computational requirement is low and independent of data window length. A Coriolis flow metering example is used to illustrate that Prism signal processing is suited to a wide range of resonant sensor systems, and can be used to provide a step change in measurement update rates compared with conventional FIR techniques.
