I can confirm that the choice of 75 Ohm for telecom use indeed is because of the low attenuation. The first use of coax was for "Carrier Frequency" systems, where a number of telephone conversations were AM modulated on individual carriers, usually 4 kHz apart. -- Poul-Henning Kamp | UNIX since Zilog Zeus 3.20 [EMAIL PROTECTED] | TCP/IP since RFC 956 FreeBSD committer | BSD since 4.3-tahoe Never attribute to malice what can adequately be explained by incompetence. _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
