A system design and theoretical foundation for QC-THz signal generation are presented. The proposed QC-THz system consists of commercially available photo-conductive antennas used for transmission and reception of THz waves and a custom-designed QC optical signal generator, which is based on a fast optical frequency sweep of a single telecom distributed-feedback laser diode and unbalanced optical fiber Michelson interferometer used for a high-frequency modulation. The theoretical model for the proposed system is presented and experimentally evaluated. The experimental results were compared to the state-of-the-art continuous-wave THz system. The comparison between the continuous-wave THz system and the proposed QC-THz system showed the ability to transmit and receive QC-THz waves up to 300 GHz. The upper-frequency limit is bounded by the length of the used Michelson interferometer. The presented design of THz signal generation has a potential for industrial application because it is cost-efficient and can be built using commercially available components.<\/jats:p>","DOI":"10.3390\/s22124448","type":"journal-article","created":{"date-parts":[[2022,6,13]],"date-time":"2022-06-13T06:01:44Z","timestamp":1655100104000},"page":"4448","source":"Crossref","is-referenced-by-count":0,"title":["A Novel System for Quasi-Continuous THz Signal Transmission and Reception"],"prefix":"10.3390","volume":"22","author":[{"given":"Andrej","family":"Sarja\u0161","sequence":"first","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, University of Maribor, Koro\u0161ka Cesta 46, 2000 Maribor, Slovenia"}]},{"ORCID":"http:\/\/orcid.org\/0000-0002-6469-3577","authenticated-orcid":false,"given":"Bla\u017e","family":"Pongrac","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, University of Maribor, Koro\u0161ka Cesta 46, 2000 Maribor, Slovenia"}]},{"given":"Du\u0161an","family":"Gleich","sequence":"additional","affiliation":[{"name":"Faculty of Electrical Engineering and Computer Science, University of Maribor, Koro\u0161ka Cesta 46, 2000 Maribor, Slovenia"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Lee, Y.-S.
