> "But it is humorous when the TDA2002 is often referred to as a replacement for the LM383. As a matter of fact, the LM383 is really a reverse engineering of the TDA2002. Credit should be given to the design engineer Bruno Murari who was working for SGS at the time. He was the one who came up with a way to do an automotive power amplifier using only five pins."

This first paragraph is almost gibberish to me. In a good way. I just find it humorous that there are so many in-the-know words here.

Please don't be proud of ignorance.

TDA200 and LM383 are obviously product or device names. Bruno Murari is obviously a person's name (a design engineer, as the sentence points out!), SGS is obviously a place where one works, likely a company.

You should have no issues with the term "reverse engineering" if you are on Hacker News. So that only leaves "automotive power amplifier using only five pins". You probably know what "automotive" and "five pins" means, though, so even less than that.

And then it's absolutely obvious that you won't know what a "power amplifier" is if you don't have some connection to electrical engineering, but it's useless to point that out. Imagine if every electrical engineer did that on articles on biology, chemistry or economic sciences.

Or to put it another way:

These are names of things. The sentence structure makes that clear, and makes it clear how they relate. They are not "in-the-know" terms that are lacking definitions. It is not gibberish, just like the sentence "Jane gave Sue a letter from Bob" is not gibberish, even though nobody defined "Jane", "Sue", or "Bob".

I don't do any analog work, so I wasn't familiar with the LM383 but it made perfect sense to me.

From the article, I knew the LM383 was a 5 lead audio amp. From context in the sentence it was clear that the TDA2002 is a predecessor of the LM383. I don't know who Bruno Murari or SGS are, but again, context makes it clear that Murari worked at SGS when he designed the TDA2002.

What part did you find to be gibberish?
