Re: Why are Coaxial cables 75 or 50 Ohm?
This list seams to want to be a place to be petty - it's not for me - bye Doug

Re: Why are Coaxial cables 75 or 50 Ohm?
uhhh.... yeah... well, the uhh, "subject" header does sorta state the question pretty plainly. but I do get your point, I did sorta forget to address my response to the person asking the question and

choke
Hello, I'm a new addition to this group. 1215 members? wow! I had to see what all the commotion was about. A question to get rolling: How does a choke work? How are they made? thanks. Steve.

Re: PIC resources
In the case of the question about where the charge in a capacitor lies - yes, we should ask the physics group. - mark them has belong to do belong as

Steve, Since you didn't quote or paraphrase I have no idea what question you've been wondering about. Jim

angtengchat, Yeah, and it's ALL physics, so let's just have one group, physics, and we'll discuss everything there. -Mike _________________________________________________________________ Get your

Re: PIC resources
Mike, Well, list groups are not necessarily so specialized that they don't overlap topics. I would say that the group owner should decide but I see nothing off topic about micro controllers. Unless

Why are Coaxial cables 75 or 50 Ohm?
hiya.. After working in the RF realm for many years, I had begun to wonder about this same question... after looking around on the WWW for a while seeking an answer, I came across a document which

Re: Not amused (was - Bomb)
It doesn't sound like censorship to me. It's only censorship if the forum is a viable place to discuss that topic. This isn't an open roundtable. What's the point of this being an electronics forum if

Re: PIC resources
Yes, microcontrollers are electronic devices, but the discussion of them has generated so much traffic that they have their own group. Should we discuss electronics on the Physics group? -Mike

Re: Parallel Port Interfacing
You have an FPGA in the design. What is the FPGA doing that it cannot communicate with a lowly parallel port? parallel Now

Re: Parallel Port Interrupt
How's this: Interrupt Enable Bit The parallel port interrupt was intended to allow interrupt-driven transmission of data to a printer, but is not used by DOS and BIOS. Versions of OS/2 prior to Warp

Re: Componet values for Switch mode power supply?
Yes there is an easier way. There is a simulation package from Linear Technology. It is a free spice simulator tailored for fast simulation of switching power supplies. You can add one of their parts

Re: Not amused (was - Bomb)
Hi guys, Curtis here. I've been watching this "bomb" thing go around (and around ... and around) I've gotta say something ..... I know everyone will turn around ... and ask "OK Curtis... so whose side

Re: lightning
Rachel, This is correct. A DC current flows through the entire conductor. As the frequency rises, the current moves out of the center of the conductor towards the surface. This is called "the skin

Re: audio switching
Gil, Go look at the "Analog Devices" (www.analog.com). They have some very interesting stuff - but they also have some analog switches designed specifically for what wou are doing., specifically the

Re: audio switching
I Hi! It all depends on the electrical characteristics of the signals you wish to switch. A transistor solution is simple and cost effective for higher currents. If you need a switch for small

audio switching
Hi, Another beginner here. Here's my question: I need to make really what amounts to no more than a 6-Pole 2-Throw switch for line-level audio signals. Although I could do this mechanically, I was
