The word "BASE" in [[Ethernet physical layer]] standards, for example [[10BASE5]], [[100BASE-TX]] and [[1000BASE-SX]], implies baseband digital transmission (i.e. that a [[line code]] and an unfiltered wire are used).<ref>IEEE 802.3 ''1.2.3 Physical layer and media notation''</ref><ref name="IEEEGetProgram">{{cite web|title=IEEE Get Program|url=http://standards.ieee.org/about/get/802/802.3.html|archive-url=https://web.archive.org/web/20101125111240/http://standards.ieee.org/about/get/802/802.3.html|url-status=dead|archive-date=November 25, 2010|website=[[IEEE]]|publisher=IEEE|access-date=29 March 2017}}</ref>
