YT2095 Posted February 23, 2004 Posted February 23, 2004 yes if it`s Off Topic from the OP. it`s gone on long enough.
YT2095 Posted February 23, 2004 Posted February 23, 2004 as is #4 as it implies induction on even broken things, therefore demonstrating that effects on a circuit (no matter how simple or broken) is a distinct possiblity. again, nothing more, nothing less
Sayonara Posted February 23, 2004 Posted February 23, 2004 It only implies that if you already know how the effect works. If you don't (can you say "original poster"?) then it doesn't imply anything. I think that's what MrL was trying to communicate. Post #4 says "this is a fact [insert fact]. This happens [insert observed effect]", without explaining if or how they are linked.
YT2095 Posted February 23, 2004 Posted February 23, 2004 I credit them with alot more sense it would seem than you or mrl then. I`m also quite confident that if I say something that someone doesn`t understand, they would ask. but since I used plain english in it`s truest form barring typos or slang (fone), it will hardly be neccesary
Pinch Paxton Posted February 23, 2004 Author Posted February 23, 2004 Oh well not to worry. I was just concerned that I am in a triangulation of the Mobile Phone Antennas, or whatever they are called, and the noise keeps me awake. I also had a mouse that got cancer, so I am concerned. Maybe my bridge is filling with radiation or something. My jaw does not open fully, and the doctors cannot explain it. Just a few things on my mind. Pincho.
YT2095 Posted February 23, 2004 Posted February 23, 2004 it`s quite possible that the bridge (there to give a more correct form to tooth allignment) maybe causing pressure in your jaw bone? It seems unlikely any electrical currents induced in the metal will have such an effect, I expect he`s covered the possibility of infection perhaps, I know I had one from a bad tooth the once and it blacked my eye and gave me horendous earache as for hearing it, it`s quite possible that it is causing harmonics within the metal structure, but the radiation cannot "build up" a bit like opening a microwave door, as soon as the power is off there no EM or danger. the most you`ll get will be a very weak current passing through it your pet could have been pure coincidence (we all die of something). if you`re that worried, call the environmental health agency and express your concerns, they will test it out for you, it`s their job
JaKiri Posted February 23, 2004 Posted February 23, 2004 Explanation of the effect, btw: The signal from the phone can induce a current in a wire, much the same as a TV signal inducing a current in a Yagi Array (or 'aerial' if you prefer). The frequency of the signal determines the frequency of the sound, and the pulse length is the same in both. However, this only works in powered speakers, because the amount of energy transferred in the wave is absolutely tiny.
YT2095 Posted February 23, 2004 Posted February 23, 2004 the frequency of the signal does NOT determine the sound, the PWM does. and it will induce currents in anything that makes a circuit powered or otherwise, so long as it`s a circuit (closed loop). {edit} and I don`t know why you chose a yagi type when a simple dipole would have sufficed, there`s nothing fancy about yagis other than directionality DB gain and rough filtering due to SWR configurations?

They tested picking up radio on fillings. It is not feasible. What is likely is that different types of fillings and saliva are acting to make little sparks. About computer speakers, my friend had one that you could listen to the radio on, and my aunt had a phone that played Cuban propaganda along with the dial tone.

I never said it wouldn't induce a current, just that it wouldn't make a noise.

Most TV aerials are yagi arrays.
wolfson Posted February 23, 2004 Posted February 23, 2004 Alot of people in my area have 2 Stack 2 Bay Vertical array aerials.
Sayonara Posted February 23, 2004 Posted February 23, 2004 If MrL had chosen "simple dipole" as his example, one might well say "I don't know why you didn't choose Yagi". It's not really important, is it?
YT2095 Posted February 23, 2004 Posted February 23, 2004 a Dipole is the most simple of all twigs (antennas) 1 up 1 down. the top receives the other is the ground plain for SWR. yagis get too complicated. yes, it makes a difference
Sayonara Posted February 23, 2004 Posted February 23, 2004 Are you saying the same effect (read: 'effect', not 'cause' or 'process') does not occur in each?
YT2095 Posted February 23, 2004 Posted February 23, 2004 no it doesn`t or at least not in the same way, and a yagi would be crapest of all examples as they`re based loaded coils (hence the DB gain) and will send RF to the set converted. a dipole is a much more realistic example and considerably easier in comparison to teeth bridges. anyway, I`m sure he wont mind me correcting him, after all, he is the one to point out Scientific accuracy and the use of approriate terminology for given subject
alt_f13 Posted February 24, 2004 Posted February 24, 2004 Just a point of interest: the UKs most widely used cell frequencies are 900MHz and 1.8GHz. For North America its 800 and 1900 MHz. And when selecting a service, go for the ones that use low frequency, digital signals. What does PWM stand for BTW? Pulse [word (width/wave?)] Modulation I'm guessing.

I very specifically said "effect, not 'cause' or process'" (because the latter two weren't relevant to my question). By saying "or at least not in the same way" and "a yagi would be crapest of all examples", you're acknowledging the same effect does occur. So although a Yagi might not be the best example, it's just as valid as an example. I think we can probably agree you didn't so much correct MrL's explanation, rather you enhanced it
Atlantic Posted March 1, 2004 Posted March 1, 2004 microwaves are transverse, you can't hear transverse waves. The ultra high buzz that you hear (part of it is ultrasonic), its just a sound (longitudial) that is generated in the CRT.
