Re: [time-nuts] Skilled Math Editor(s) Needed
Hi Perry, I have done the exercise on another book. The copyright holder released the material under Creative Commons license, so that helped to remove any issues and let us focus on the content. We put it on github and from the OCR original I did a translation into LaTeX. Even on the third or is it fourth run-through we still fix OCR issues and original faults. The benefit of using github and a good license is that we got folks joining us as we where working, some have done minor contributions and others have just joined the theme, contributing on stuff they feel they can contribute. One for instance just reviews text, but oh what he contributes to clean things out. It turns out to have been a very efficient way of operating. For some stuff I have done some heavy-lifting to resolve issues, and others have then come in to clean up stuff. I have then tried to have people focused on the right tasks. Others come in to focus on the layout of the book, being skilled in Layout and LaTeX. This is the way forward for projects like this.

Re: [time-nuts] Skilled Math Editor(s) Needed
It was not my intent to suggest that Perry should continue the work using Latex. I was merely considering the most effective and efficient way to complete this undertaking, whoever elects to pick it up. The original is written in English so an extensive knowledge of French isn't required. At 616 pages (according to the Amazon listing), or 1567 pages ( according to the google books entry) the task isn't perhaps quite as daunting as I originally thought. Even so it may take 1-2 years at 3 pages/day.

Friends in time, Perry has apparently reached a major change in his life, perhaps because of a doctor's diagnosis - but there are zillions of other reasons. It seems to me that he is looking for someone to pick up his project and run with it. Advising him on the ways he could continue is probably not useful. He needs someone to take the baton and take it further. I say this as one who has downsized by 75% in order to move into a life care community after my wife and I had cancer scares and no long term care insurance. A cousin was the copy editor for Gone With the Wind and other Doubleday books. I seem to have inherited some of those genes. But I can't tell a bad equation from a good one, and my French ended in High School. Happy new year to the best list on the Internet.

The largest error source are characters that look very similar which can be aggravated by the particular font used the lower case "L" (i.e l) and the number "1" are often mistaken by OCR engines . For years HP/Agilent for example used a font where these two were identical. Other sources of OCR misreading "I" (both upper case "I" and lower case"i" ) mistaken for the "L" and "1". Other common errors are "8" and "B"; "6" and "G" ,and so on.

Re: [time-nuts] AM vs PM noise of signal sources
Attila, Since we talk background noise and white noise, the amplitude is the same for AM and PM. This is part of the AM/PM lecture of NIST that I know you have participated in at least once. Under the assumption of low modulation index, which is fair assumption for background noise compared to most carriers, both the AM and PM noise of a certain side-offset has two side-band peaks, a lower and an upper. The big difference is that for AM they have the same polarity and for PM they have opposite polarity. Thus, they are as orthogonal as common mode and differential mode. Noise on both absolute frequencies will combine and contribute to the same AM and PM levels. It's that simple. So, for that scenario you know one you know the other. Now, for actual sources this is no longer true. The AM noise can be much higher, which is why it can be a real danger to the PM noise if there is a AM to PM noise conversion. One source of such conversion can be the amplification stage, but another could be a mistuned filter, which have different amplitudes of the side-bands, which can create conversion as the balance does not balance the same way anymore. Also turns out that the nitty-gritty of cross-correlation spectrum analysis also occurs in AM-to-PM conversion and cancellation. This I had not paid full attention to, but got reminded off at the workshop. Thus, they are tied together and should be measured and understood together.

Re: [time-nuts] AM vs PM noise of signal sources
Hi Just as with PM noise, AM noise is a “that depends” sort of thing. The first dependency is on your test gear. If the AM noise was well below the PM noise, would you be able to measure it? Equally, if you are doing something like a diode detector - can it measure AM below XXX dbc? If the detector is only good to -120 dbc/Hz, you aren’t going to “see” -130 …. Noise on output state supply lines can generate AM. In some cases the stage is a better AM modulator than PM modulator. Limiting (like with a logic gate) is not going to pass AM noise well. That combination can make for some “interesting” noise profiles. One “old time” assumption for wide band noise is that there is no process that will generate AM independent of PM. Thus they will always be in an equal power relationship. The key phrase here is wide band. Think in terms of notching out the carrier and looking at the result on a spectrum analyzer in this case. One of the classic arguments for an AGC or for certain types of limiters in oscillators is AM to PM conversion. The concern here is “close to carrier” rather than far removed. There certainly are examples tossed around where AM noise is significantly higher than PM noise at low offsets. So, no data that I can share. Maybe a few things in there will be of help.

Re: [time-nuts] Stable32 now available
Dave I looked at the link. Expecting the typical $132 and up... Its Lulu and $19.95. I have ordered books from them before and been very happy with the product. I can not answer your question on how up to date it is. But will look at the pdf. If its even a bit decent the $ investment is cheap for a real book.

Jelen Thank you for informing us about Stable32. I have been busy downloading details. I was surprised by the size of the use manual at some 348 pages. I believe I have a very long way to.

Re: [time-nuts] Stable32 now available
Hi If the code also *is* part of the deal (or becomes part of the deal) I would suggest that there are a series of papers in the “to be written” category about how it does what it does. I have no idea what the code looks like so this is in no way a knock. It’s a big program with a lot of research backing up it’s internals. It would be a “first ever” if all the footnotes and flow charts were already in the code. Bob > On Jan 2, 2018, at 6:05 AM, Magnus Danielson > wrote: > > Hi, > > Very cool.

Re: [time-nuts] Stable32 now available
Hi, Very cool. That I ended up paying for my copy is another thing. Now, the code needs to be maintained. I personally also would like to see it run natively on Linux, it does run on Linux under Wine. The best way to maintain the code would be for UFFC to put it on github, preferably with a suitable license. That way a shared community of people can contribute to it. I think we have enough experienced programmers here to nurture such a project over time. If we do that, I think Bill and UFFC will get the best support into the future from the community.
