Prob. a very basic Q re: capacitors

Opamps are often designed for open loop gains of 80-100dB but that'll collapse when you venture anywhere beyond the audio range. I don't use opamps much in signal paths but the last one had to deliver up to 100MHz and the client wanted it nice and flat. Their definition of flat was

Yep, "decline to quote" is a common term. Insurance agents may not be familiar with it but underwriters sure are.

There is always that risk. Handle breaks off, box hits someone. If I hadn't been born I could not have designed the front end, the machine wouldn't have become a product, there wouldn't have been a handle that could break off, and so on. We have some serious problems with litigation in our country. To the point where some products are never built and many jobs are never created because of that problem.

No matter what the gain, two stages are best... because they are amenable to pole-splitting style compensation.

What was his name?

Or hang around Usenet & change their screen name a half dozen times a day.

What you have to say from your soapbox is worth listening to. :-)

Unlike some others' soapboxes. :-(

BTW - the ultrasound/stent/plaque discussion was fascinating.

Sometimes you can get some discounts on a few items. It also is fun to pull it out when someone calls one "sonny" ;)

They do send me Life insurance mailings, but other than that, I heven't seen any increase in junk mail. I can;t yet take advantage of any of the Medicare insurance, but it's definitely something to keep in mind - I think the best things only kick in after you reach at least 62.

HTH

Thanks. Still, sometimes I do crash through my soapbox ;-)

When you are in the cath lab though it's quite sobering. They use intravascular ultrasound only on difficult cases. You see a lot of gross stuff on the screen where you quietly ask yourself "How come this guy is still alive?". The CEO of one of my clients has stopped eating any pork or red meat because of that experience. I couldn't quite bring myself to that (yet).

Hint to anyone thinking about going into this field: Standing in a catheter lab 10-12h/day in a lead vest is tough on your lower spine. Really tough.

I missed that one...

The problem with getting on a spoapbox, tho', is that sometimes it's still soapy and one falls crashing onto one's posterior

I, for one, won't be "soapboxing" as much once my texts arrive ;) . I've gotten some really good info from folks here, and in sci.electronics.basics, so I'm looking forward to meshing it all with what the texts can tell me. ((The horrors of self-teaching ))

Today, I'll be doing actual glass-work :o , and working up a new design that popped into my head last night - do it in 3D and then scoot it over into aprogram that unwraps/disassembles the 3D model and lets you print a "cut-outable" thing that you can assemble; assembling the paper model gives me a clue re: how difficult it'd be to assemble the glass item, plus, sometimes things can look a lot better in 3D than they come across in 'real-D' so to speak. It keeps me out of trouble ;)

Kris,

I imagine you've posted this and that I missed it, so... which textbooks did you order?

I don't think I did, post them, actually - thanks for asking: "Practical Electronics", which I'd asked about here; and on a lark, based upon the Reader Reviews, "All New Electronics Self-Teaching Guide (Wiley Self Teaching Guides)".

Meanwhile, back to making lots of little shards of ground glass

Cool, let us know what you think of them.

If you want a more traditional textbook, I have a spare copy of Sedra & Smith

OK, will do! "Practical El." was shipped today and is supposed toarrive by

I'm hoping they'll be a good bridge between the bare basics, and advanced knowledge.

One book I was very disappointed with is "Electronics for Dummies". I still had to refer back to another extremely basic book (and the two combined still fell short in terms of explanations and going a step past the basics). There is also "Electronics Projects For Dummies", and I think that a good 80% of "EFD" should have been moved over into the "Projects" book, and replaced with more fo the info needed to understand and manipulate what's going on in electronics devices. IMO, "EFD" was a waste of money.

I hit "Send" by accident (my finger twitched on my touch pad while mousing)

Two online book that had been recommended (either here or in sci.electronics.basics)": Lessons In Electric Circuits, Volume I . DC Fifth Edition The link to it wasn't saved along with the PDF, so I can't put it here. It's decent but I have to print out the most-useful chapters - I don't do well with online books ((probably too many decades of printed material - old habits die hard. Plus, I can't scribble in the margins - I like to note cross-references (book and pg number), elaborations I might have foundto the book's explanation, copy in relevant diagrams, and other sorts of notes. I can also prop a book up on the exercise machine, as opposed to having to sit at the computer desk. A book also doesn't ahve my computer's

I also got the Navy manual PDF - it's OK but geared towards different sorts of applications, and I need a bit more in the way of explanations.

That's generous!, and much appreciated, but I'd pay you for it - that's only fair. First, tho' I'll see how these two books work out. And, since I pretty much have one specific project in mind, I think that it'd be far more fair for it to go to a real electronics student. Yeah, I know it sounds weird , but I have to do what I believe to be fair :) ((Which is why I'll never be rich ))

Meanwhile, reviews of the otehr tow books to follow, once they arrive and I work with them a bit :)
