The purpose is to establish new stability criteria in terms of linear matrix inequality (LMI) such that fixed-point state-space digital filters with saturation nonlinearities in the existence of external interference ensure passivity performance with its storage function. The presented results not only ensure state strict and input state strict passivity in the presence of external interference but also confirm asymptotic stability without external interference. The obtained conditions for fixed-point state-space digital filters are based on passivity properties and, hence, are quite novel to previously proposed criteria. Finally, simulation results are given to demonstrate the effectiveness of the proposed work.<\/jats:p>","DOI":"10.1177\/0142331217746491","type":"journal-article","created":{"date-parts":[[2018,2,1]],"date-time":"2018-02-01T05:54:26Z","timestamp":1517464466000},"page":"4246-4252","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":17,"title":["New passivity results for the realization of interfered digital filters utilizing saturation overflow nonlinearities"],"prefix":"10.1177","volume":"40","author":[{"given":"CG","family":"Parthipan","sequence":"first","affiliation":[{"name":"Indian Institute of Information Technology Design and Manufacturing, Kancheepuram, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xavier S","family":"Arockiaraj","sequence":"additional","affiliation":[{"name":"Indian Institute of Information Technology Design and Manufacturing, Kancheepuram, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Priyanka","family":"Kokil","sequence":"additional","affiliation":[{"name":"Indian Institute of Information Technology Design and Manufacturing, Kancheepuram, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2018,2,1]]},"reference":[{"key":"bibr1-0142331217746491","doi-asserted-by":"publisher","DOI":"10.1016\/j.aeue.2010.12.001"},{"key":"bibr2-0142331217746491","doi-asserted-by":"publisher","DOI":"10.1080\/00207217.2012.743083"},{"key":"bibr3-0142331217746491","doi-asserted-by":"publisher","DOI":"10.1007\/s00034-012-9520-0"},{"key":"bibr4-0142331217746491","first-page":"61","volume":"26","author":"Anh NT","year":"2010","journal-title":"VNU Journal of Science, Mathematics \u2013 Physics"},{"key":"bibr5-0142331217746491","volume-title":"Classical Network Theory","author":"Belevitch V","year":"1968"},{"key":"bibr6-0142331217746491","doi-asserted-by":"publisher","DOI":"10.1007\/s11045-010-0110-7"},{"key":"bibr7-0142331217746491","doi-asserted-by":"publisher","DOI":"10.1109\/31.135754"},{"key":"bibr8-0142331217746491","doi-asserted-by":"publisher","DOI":"10.1137\/1.9781611970777"},{"key":"bibr9-0142331217746491","volume-title":"Two-dimensional Imaging","author":"Bracewell RN","year":"1995"},{"key":"bibr10-0142331217746491","unstructured":"Butterweck HJ, Ritzerfeld JHF, Werter MJ (1988) Finite wordlength effects in digital filters-A review.
