Of course it will.
Given a linearly distorted signal without too much noise, there is a reciprocal function that undoes the distortion. It's "the deconvolution problem" to find that reciprocal function.
The deconvolution thing is one of the mathematically "ill-posed problems." Which makes it fun to play with.
I can't see glass weaves in a 20 GHz TDR on a cheap FR4 board.

Word salad.
Deluded nonsense.
The wavelength of a a 20GHz signal in FR4 is about 1cm. The weave in the glass fibre cloth is at about 1mm. It won't be all that obvious - perhaps more so if you hit an exact multiple of period of the weave, and your board turns into a diffraction grating.

Didn't Pease die in a car accident in his VW Bully on the way home from Jim's funeral?
Even weirder, he had written a publication on how to avoid car accidents, IIRC.

I visited the DeLaval turbine plant and was not allowed to turn a trimpot on my own controller. I had to tell a union guy which way to turn it.

Pease lived on Miraloma street near my house. His front yard and most of the parking spaces on the street were full of various rusting VWs.

I was not allowed to replace a defective capacitor I located in ground equipment in ESA when they called me to help with trouble shooting. I said: Look we have that capacitor, can replace it now. But a whole procedure had to followed. Seems it was replaced as thing went OK later! Was a dead short coupling capacitor.
IRC in broadcasting I have cheated by getting parts from the local electronics shop, things were also often time critical. We had a large parts store, but not always everything in stock.
But then I also have a paper that says: 'Technician in higher electronics' And an other one 'NERG technician'.. And an other one 'broadcasting engineer' etc etc That last one from the exams I did after getting a 6 month training in broadcast equipment, satellite systems, audio, video, studio management, what not in the school banks .. All payed for by the national network. Nice trip to Brussels headquarters after passing the exams, then straight to work.
No, they protect people.
In my case that was not bc of unions. I did not have the annual exam / paperwork.
Sometimes, it goes over the top. In a previous life, I did sth. for a huge Berlin based manufacturer of photo typesetters. The engineers were not allowed to do their circuit drawings in Orcad STD themselves; that was reserved work for the technical drawing people who knew nothing about electronics.
They went bust in 1993.

Dear John Larkin:
Senses 3b for "engineer" are "[. . .]; a technician." according to Della Thompson et al., "The Concise Oxford Dictionary of Current English", Oxford University Press, 9th edition, Reprinted with corrections 1998.
(Even 3b shows more than 1 sense, hence a semicolon).
Sense 1 and Sense 6 for "engineer" are similar to Sense 1 and Sense 2 for "technician".
The 3rd sense for "technician" may differ from a sense for "engineer".

A thing is good. A different thing of the same type is bad. Unions are allegedly an example of such things.
Doctor Aubrey Blumsohn alleged on this LISTSERV -
- with Subject: [DEFENDING-ACADEMIC-FREEDOM] NHS "Whistleblowers" on Date: Fri, 1 Aug 2014 15:57:25 +0100
-"This is mostly an academic freedom issue.
Sure you all know about the great new government initiative to pretend to prevent bullying of NHS whistleblowers who have spoken out about care in academic medical centers.
Above is a call to examine in detail six of those cases. Sometimes the excuses are along the lines of those expressed by [. . .] in relation to the Chapman case "too long ago" "what can be done" (even though, in that case, the Union involved still exists, and its officeholder who were involved are clearly working in government). Plenty of questions and not many answers.

I was reading this morning Lufthansa is now hit by big strikes...
Yes, same here where I worked in The Netherlands, drawing department! I provided them with sketches.... We used an external company to make the PCB layouts, some ISA card stuff back then, I tested the circuits on veroboard before that.. Never a problem. Small boards we etched ourselves .. Been doing that at home too. In that company we worked close with IBM, their office just a mile away.
I worked for many companies, both here and all around the world, including UK and US. And had my own TV repair shop in the nineties. That is actually where I got my first computer, a Sinclair ZX80, started coding!
Yup, 2011 was a bad year for that. Jim, Bob, Tony Siegman (who posted as AES here and in sci.optics ), and Dennis Ritchie.
He was still on the property iirc.
A really turgid book on avoiding car accidents, unfortunately (I bought a copy and threw it away.)
Then he died by driving the least crashworthy car in memory into a tree.
A good guy. May God keep him in memory eternal.

Yes, a Beetle.
He did at that, and I read it. Bought it directly from Pease at a lecture in the Boston area.
He was very big on wearing seat belts, but was unbelted when he crashed on the way home from Jim W's funeral.
My theory is that he drank too much fine wine at the funeral, and forgot to buckle up, and may have simply fallen asleep while driving home.

Far from it. But American bosses really don't like them. When I was briefly and minimally active as a trade union officer in the UK I got to hear a lot about how pathologically nervous American companies with British subsiduaries were about any kind of trade union activity in those subsiduaries. Most of the stuff I did get involved with was about restraining bureaucratic half-wits in the personnel department from bullying employees they didn't like. All the trade union reps did was push the disagreement up to the next level of management, who weren't all that clever either, but rational enough to recognise irrational behavior when it was spelled out for them.
You do seem to be a dummy in this area. I'm not.
The joys of decomposing a complex repetitive signal into it's component sines - the discrete Fourier transform (or if you do it with the minimum of arithmetic effort, the fast fourier transform) aren't unknown to me.
Equalisation is just boosting and shifting the components that have been been attenuated and delayed. If you printed circuit board introduces lot a of random and frequency dependent little delays it's not easy to find the correct correction function.
