Talk:Impedance bridging

From Wikipedia, the free encyclopedia

[edit] Article name

I moved this to impedance bridging since it gives this idea that it is the "opposite" of impedance matching, but the term "voltage bridging" i think is more common.

Also they are not opposites really. One maximizes power and one maximizes voltage. Not opposites.

Also to differentiate it from a bridged amplifier, in which two positive outputs are inverted from each other and used to drive a load in a floating type configuration. not the same thing.

Also I am going to keep editing these. - Omegatron 20:54, Jun 23, 2004 (UTC)

Is this an acccepted term in the industry?--Light current 03:29, 16 December 2006 (UTC)

No. We kind of made it up, from the common term "bridging". Do you know of a better one? — Omegatron 04:08, 5 January 2007 (UTC)
No, but I didnt think neologisms or original research (terminology) were allowed 8-)--Light current 17:48, 5 January 2007 (UTC)
The only terms I can think of is 'parallel connection' or 'tapping' as in phone tapping--Light current 18:53, 5 January 2007 (UTC)

It's not actually made up, but it's not commonly referred to by name:

  • "Calculation the damping of impedance bridging or matching an interface connecting Zout and Zin""[1]
  • "If the load impedance is 10 times or more the source impedance, it is called a "bridging" impedance. Bridging results in maximum VOLTAGE transfer from the source to the load."[2]
  • This might be related?
  • "High-impedance bridging input does not load signal source"[3]
  • "High impedance/bridging" inputs [4]
  • "High-impedance bridging inputs allow connection from either high or low impedance sources."[5]
  • "Actual output impedance is 100 ohms (47 ohms unbalanced) and the TB-6 "Mic-All" amplifiers will drive virtually any line load from 600 ohms to high impedance bridging!"[6]

"High-impedance bridging" might actually be a better term? — Omegatron 19:14, 5 January 2007 (UTC)

Since the term 'high impedance bridging' is in the literature, I think we could use that. Voltage bridging merely redirects to impedance bridging, so its just a matter of deleting the voltage bridging page. —The preceding unsigned comment was added by Light current (talk • contribs) 20:11, 5 January 2007 (UTC).
What literature?
Why would you delete the redirect? — Omegatron 21:21, 5 January 2007 (UTC)

Here is a book that mentions "bridging" vs "matching".

[edit] "Second Device" vs. "Previous Device"

"It is a bridging connection if the second device does not appreciably load the previous device." Which is the "second" device? The load or the source? How is "previous" defined here? I'm pretty sure that this means that the source does not appreciably load the load device, but this language could be clearer. Steve carlson 23:27, 9 March 2007 (UTC)
