The next section presents the methods, which were employed in the proposed approach, for implementing the digital filter verifications shown in Section "Finite word-length effects in digital filters".
Such an approach is composed of digital-filter verification rules and the verification engine itself.
The present paper addresses the digital-filter verification problem and describes the use of a general purpose SMT-based bounded model checker for C programs, in order to verify potential problems caused by fixed-point arithmetic, on recursive filters.

They serve as basic elements and structures in varied fields of Metrology (chemical analysis, environmental investigation, medical imaging, particle observation, flow measurement, surveying), for modelling, description, simulation, error and uncertainty analysis, reconstruction, filtering, verification, and so on.
A tutorial, example-based approach is employed to present several KF issues of considerable importance in engineering practice, and to suggest some check points on Kalman filtering verification process.
For the Direct Form II filter, the verification successfully finishes without issuing any overflow failure, due to operation execution-order in this particular case.
The fourth filter required verification of gene expression differences by reverse transcriptase PCR (RT-PCR) in C57BL/6J and DBA/2J, and in a two BXD RI lines that had low and high transcript abundance by microarray.
The intraoperative identification of tumor tissue was performed by application of ALA prior to surgery and subsequent observation with the operating microscope with excitation using a violet-blue (375 440 nm) xenon light, a 455-nm long-pass filter and verification by analysis of fluorescence spectra.
