However, since commonly used DACs have limited accuracy, some artefacts can be observed in data streams, especially in systems designed for continuous, long-term process monitoring. In this paper, the authors\u2019 experience with data enhancement using a fibre-optic rotational seismograph (FORS) operating in a closed-loop mode is presented and discussed. Generally, two kinds of enhancement are described. The first one uses suitable filtering techniques adequate for FORS noise investigation, as well as a suitable data resampling method for transmitted data file size reduction. The second one relates to the artefacts observed during data recording in real time. The recording starting point is triggered when the detected signal exceeds a middle signal level and, therefore, the existence of artefacts generally disturbs the recording process. Although the artefacts are easily recognised by human eyes even at first sight, their automatic elimination is not so easy. In this paper, the authors propose a new concept of signal filtering to solve the above problem.<\/jats:p>","DOI":"10.3390\/s22228673","type":"journal-article","created":{"date-parts":[[2022,11,10]],"date-time":"2022-11-10T21:22:02Z","timestamp":1668115322000},"page":"8673","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Post-Processing of Raw Data Recorded Continuously Using a FORS\u2014Fibre-Optic Rotational Seismograph"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5153-2398","authenticated-orcid":false,"given":"Bartosz","family":"Sakowicz","sequence":"first","affiliation":[{"name":"Department of Microelectronics and Computer Science, Lodz University of Technology, 221 W\u00f3lczanska St., 93-005 Lodz, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marek","family":"Kami\u0144ski","sequence":"additional","affiliation":[{"name":"Department of Microelectronics and Computer Science, Lodz University of Technology, 221 W\u00f3lczanska St., 93-005 Lodz, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7766-0969","authenticated-orcid":false,"given":"Micha\u0142","family":"Dudek","sequence":"additional","affiliation":[{"name":"Institute of Applied Physics, Military University of Technology, 2 gen.
