message: Electromagnetic interference redirects here, but it seems like radio frequency interference is a type of electromagnetic interference. -- Kjkolb 01:13, 7 January 2006 (UTC)

thread_title: Removal of redundant and unsourced additions

message: The article on electromagnetic compatibility gives a much broader (and more correct) description of EMI than is discussed here. I think this arcticle should be restructured and expanded acccordingly. Any objections? -- Cheers, Steelpillow (Talk) 14:20, 28 January 2009 (UTC)
replies: text: I think electromagnetic compatibility is a very well done article. Thanks for volunteering the much needed improvements here. LuckyLouie (talk) 14:38, 28 January 2009 (UTC)
thread_title: Scope of article

message: "If EMI for electronics or astronomy is reduced so is happened to RFI. (EMI/RFI in Roumanian language, 2005 - 2009)."
I cannot make sense of this sentence or even what I assume is a reference in parentheses. Would someone fix this problem?
I'm sorry I can't do it myself (due to Adult-onset Still's disease, my daily fever creeps up with any activity, so I have to pace myself carefully) and I appreciate the hard work of the person who can and does fix it. Thanks! Geekdiva (talk) 09:51, 8 September 2009 (UTC)

message: The bottom half of this article had a mixture of useful commercial links with information and links to pages that are principally advertising products / companies. I have tried to impartially remove those with little information content and a more commercial bias. I can see that this could be a contentious issue, if there are any concerns, please feel free to revert, replace or get in touch.Roggg (talk) 10:27, 31 May 2012 (UTC)

thread_title:  EMI Manufacturers 

message: This is rather misleading. The key is that something non-linear is acting as a Detector. It's not just an Integrated circuit, but any non linear device.  eg The Cats-Whisker detector in your grandfather's Crystal Set radio. I've edited out the technical errors and bad grammar.119.18.11.19 (talk) 07:26, 8 April 2014 (UTC)
thread_title:  Integrated circuits tend to demodulate high-frequency carrier signals 

message: I suggest that EMC_problem_(excessive_field_strength) is merged with this article.
"EMC problem" is a useful article title. One can suffer from an EMC Problem, similar to a Health Problem, a Hearing Problem or a Wild Animal Problem, but this doesn't mean these need their own pages.

replies: text: It's unclear why the proposal is to merge to Electromagnetic interference rather than Electromagnetic compatibility (EMC), as these are different concepts. Given this, and the lack of support over almost 3 years, I'll close this proposal. I'll link from the EMC page; I'm neutral on whether a merge to the new target is actually necessary. Klbrain (talk) 11:14, 23 July 2017 (UTC)
thread_title:  Proposing merge of EMC Problem 

message: There is rather a long list of references on the Wiki EMI page, some very specialist. I suggest that this list should be rationalised if possible and that a good text book on the subject of EMI be used for the majority of the references. For example 'EMC for Product Designers' (EMC= Electromagnetic Compatibility) by Ted Williams is regarded as a bible in the EMI field in the UK. It covers the subject from a high level and also technical depth. It is also clear and concise. I know this is sacrilege but I really don't think for a specialist field like EMI that the OED should be used as a reference; it's too general. CPES (talk) 05:43, 12 September 2015 (UTC)
thread_title:  References 

message: It is unfortunate that the term EMI is misleading as there a three fundamental forms of unwanted coupling (which is what EMI is all about): Electromagnetic, Electrostatic, and Conducted. This is a fundamental and important aspect but the difference between Electromagnetic and Electrostatic especially is not made clear to the average reader in this Wiki article. CPES (talk) 05:43, 12 September 2015 (UTC)
thread_title:  Electromagnetic/Electrostatic/conducted EMI

message: 1. The article says "On integrated circuits, important means of reducing EMI are: the use of bypass or decoupling capacitors on each active device (connected across the power supply, as close to the device as possible), rise time control of high-speed signals using series resistors, and IC power supply pin filtering. Shielding is usually a last resort after other techniques have failed, because of the added expense of shielding components such as conductive gaskets."
The article does not gives a practical example for filtering EMI. I would be nice to clarify the practical aspects and add a section with a simple schematic that explains how you filter out a signal that goes in the input of a device such as, for instance, a DC/DC converter. My understanding is that EMI filtering can be done with a combination of inductions in addition to capacitors.
2. The article mentions "Such software can find samples in time, frequency or time-frequence space that are contaminated by an interfering source".
It's not clear to me if "time-frequence" should be "time-frequency" but, even if it just makes sense to me to write "time, frequency or both".

thread_title:  Comments on the article 

message: The statement is in the 7th paragraph of the section "Interference to consumer devices," specifically that "[r]adio frequency signal quality has declined throughout the 21st century by roughly one decibel per year as the spectrum becomes increasingly crowded." However, the article cited buries the claim in weasel words. The phrasing there is "Some industry experts reckon that, since 2001, radio frequency signal quality has been falling by about 1dB each year," followed by "That aforementioned 1dB per year drop means, folk in the business say, carriers need to roll out 14 per cent more base-stations to make up the loss." I haven't been able to find a single additional source to back this up, and, given language such as "some industry experts reckon" and "folks in the business say," I find it hard to consider it a verifiable claim.  — Preceding unsigned comment added by Pbtflakes (talk • contribs) 01:49, 20 April 2017 (UTC)

message: There are some nice interference images from European TWDR due to 5GHz wifi in the references. (e.g. page 7 of ) It should be easily relatable by readers as most people have seen Doppler weather radar images. I cannot find a free image on the internet.
