jtkinney Posted March 5, 2008 Share Posted March 5, 2008 Gil has been posting a lot of interesting articles, so I thought I would post a few myself. I ordered these some time ago and just got them. I haven't read them very closely yet, so I won't comment on them until I do. Part 1. Enjoy. 6901heyser.pdf Quote Link to comment Share on other sites More sharing options...

WMcD Posted March 5, 2008 Share Posted March 5, 2008 Thank Jim, I'm running a bit low on articles to post. I'll let you take over. Smile. My advice is to pace yourself. Gil Quote Link to comment Share on other sites More sharing options...
mas Posted March 5, 2008 Share Posted March 5, 2008 Hey, that Heyser guy is talking about Minimum Phase Networks in 1969 when only a couple of months ago still others here were giving me credit for inventing the entire notion! Hmmmmmmm. I suspect someone has doctored the Heyser document! As Don Davis has oft observed: "The ancients are stealing all of our inventions!" ROFLMAO! PS. As always, the docs are most welcome!

WMcD Posted March 5, 2008 Share Posted March 5, 2008 I'll point out the old nomenclature which shows up in the Hillard article. A microphone is called a transmitter. You'll also see speakers or drivers or eaphones called receivers. I recall old movies where someone using a telephone holds the receiver (earphone piece) up to his ear. Maybe that is when using the old candle stick type telephones like Sam Spade would have on his desk or a payphone where the microphone is mounted on the box. I recall Boomac has a similar magneto crank type wall phone, last seen in the original TV Lassie series. Gil Quote Link to comment Share on other sites More sharing options...
jtkinney Posted March 6, 2008 Author Share Posted March 6, 2008 Gil, Those just happened to come in recently. I still have over 200 electronic documents on audio, several that have come from you and other members of this forum. I need to figure out which came from other sources and start posting some of the more interesting ones. I also have hundreds of ham radio related articles, but that's for another forum. Working for NASA has some privileges, as I have access to several online databases as well as hard copies of technical journals at various centers that I can get copies of. If you are looking for a certain article, let me know, I might be able to request it. Quote Link to comment Share on other sites More sharing options...
jtkinney Posted March 6, 2008 Author Share Posted March 6, 2008 mas, I didn't change anything, well not much that you didn't ask for. I will get with you about that payoff later[8-)] Everything old is new again. The next go around you might get credit again. Quote Link to comment Share on other sites More sharing options...
bigdaddy Posted March 6, 2008 Share Posted March 6, 2008 Ok I am loving audio, but that stuff just makes my head hurt. I just want to put on some music and enjoy my speakers. Quote Link to comment Share on other sites More sharing options...
