Explanation of Ferrite Symbols

I'm looking through a Ferroxcube data handbook. The symbols I see online for "Permeability dependent on frequency"

Complex Permeability as a function of frequency and use the symbols

Are these the same? If not, how are they different?

And then I just found this page that has graphs.

The graphs are labeled "Complex Permeability"

Thanks for the help, Mikek

Here's a link to the Ferroxcube data book that was used by me for this followup:

formatting link
Both Ferroxcube and incompliance contain a lot of typos that transpose the subscript-s with the quote/double-quote. The correct symbols seem to be:

??' (us') real component of complex series permeability ??" (us") imaginary component of complex series permeability ??' (up') real component of complex parallel permeability ??" (up") imaginary component of complex parallel permeability

apparently indicates that the graph applies to equally to both series and parallel permeabilities.

Thank you, 73,

Yes. Although my usenet headers send

Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit

the receiving newsreader must be able to interpret 8bit UTF-8 in order to properly display extended symbols. So, the 7bit ASCII equivalent is shown within parenthesis for the benefit of people whose newsreaders lack that capability.

Thank you, 73,

Well, I tried to fix my computer to read properly. Tools> account settings> Under 'News Account'>Server Settings>Default Text Encoding change to Unicode (UTF-8) But nothing changed. Using Thunderbird.

Although Thunderbird's not my primary usenet reader a very old version of Thunderbird (version 1.0.8 (20060417)) run from within Windows 2016 correctly displays the extended characters. My Windows 2016 installation notes indicate that nothing special was done to achieve this result.

Addendum:

One other thing occurs to me. Part of my Windows 2016 installation involves dozens of custom fonts that are not included with Windows

2016.

It posted correctly that's a subscript s not a box.

On your computer, not mine, I have a box with the numbers 20 above 9B, Readable only with a magnifying glass. Mikek

which it why I said it posted correctly.

That box means you're missing the font, or whatever it is that's needed, to support that symbol. You can usually paste the box into a web search to find out what the symbol is supposed to be. finding out which font pack is needed is harder.

It displays perfectly using Firefox and Chromium on a standard installation of Linux Mint.

It also displays perfectly on my tin newsreader in gnome-terminal on FreeBSD. It takes two parameters to make that happen. First, you must use gnome-terminal's Terminal menu item to specify UTF-8:

Terminal > Set Character Encoding > Unicode (UTF-8)

Second, you need to configure tin to use ISO-8859-1:

76 MM_NETWORK_CHARSET : ISO-8859-1

The subscript-p and subscript-s characters in my original followup were copy-and-pasted from gnome's Character Map application. Those two characters are designated as:

U+209A LATIN SUBSCRIPT SMALL LETTER P U+209B LATIN SUBSCRIPT SMALL LETTER S

It also displays perfectly on my Thunderbird on Windows 2016. My Thunderbird's configured like this:

Tools > Options > Fonts Character encodings Outgoing Mail: Western (ISO-8859-1) Incoming Mail: Western (ISO-8859-1)

Thank you,
