References

The references on this page seem to be in really bad shape, using bare URLs along with strangely-formatted citations that use descriptive passages alongside or in place of actual quotations. I will attempt to fix some of these, but would appreciate some help from a more experienced editor. pwnzor.ak (talk) 21:55, 1 July 2017 (UTC)[reply]

The reference needed for mentions of "sine wave tone" exists in Wikipedia under Audio, but it doesn't mention "sine wave tone" in particular as part of the test conducted with the test pattern, and that page needs an edit to add that information. ALL analog audio is sine wave; this particular tone spoken of here is 60 Hz which is calibrated with the specifications of the AC power supplied by electric power plants--also federally regulated to be exactly 60 Hz. It's upon that 60Hz calibration that other frequencies used in the broadcast depended on. Also true in radio broadcasting especially when going on emergency power during a power outage. If that 60Hz frequency reference was off, all the others would be as well. — Preceding unsigned comment added by DSLevesque (talk • contribs) 03:48, 5 April 2020 (UTC)[reply]

Signing off

There may be another article where this is appropriate, but since I'm here ...

An old comic strip on gocomics.com has a young child fascinated by the test pattern rather than an actual program. This led to a lot of comments, obviously unsourced, about how things were back in the day. I misread something and was going to say digital stations couldn't sign off without a lot of "recalibrating" and such. Actually, it was hard on the early broadcast equipment. Another commenter said the test patterns were used during the day when there wasn't a lot of daytime programming to help installers.

Lots of research for someone to do. Maybe me, but I find I don't have much time these days.— Vchimpanzee • talk • contributions • 18:43, 13 July 2018 (UTC)[reply]
