Flag desecration?

Might have something to do with the locales... I don't think I'd want to try to get a job in the Europe right about now...

Are you am to say what type of project it is?

As usual, it's bleeding edge. Comments next year ;-)

Ah, c'mon, in my experience *every* company likes to believe it's doing bleeding edge development!

Will be looking forward to your comments in 2007...

On KLM, no doubt, if you can get past the gate.

--- Wrong again.

With:

T = kRC

where:

Vcc k = ln ----------- Vcc - Vth

and, for TTL with Vcc = 5.0V, Vih = 2.0V, and Vil = 0.8V,

k for Vih = 2.0V will be:

5.0V k1 = ln ------------- = 0.222 5.0V - 2.0V

and for Vil = 0.8V will be:

5.0V k2 = ln ------------- = 0.076 5.0V - 0.8V

Now, since RC will be the same in both cases, we can merely divide k1 by k2 to get the spread in timing, which will be:

k1 0.222 dt = ---- = ------- = 2.9 ~ 3:1 k2 0.076

The spread is even lower using Voh instead of Vcc as the source voltage for the RC, so I'd like to see where you got your 10:1 numbers from.

Living in a area full of senior citizens ands retirees I see this all too often. They mostly fall into two groups: Those who have given up, and those who won't give up. the rest are the few that are 100% disabled, and some of them volunteer to answer phones and do other office work for a number of non profit groups because they know they have to be doing something.

The first group whines and complains just like Bill, "I applied for the CEO job, and all they offered was to sweep the floors! I'm too self important to take that kind of lousy job!" From the second group I've met retired electrical engineers working at Walmart, former business manages selling at a flea market, and others working part time at something just to keep busy. Hell, I was underemployed when I went to work for Microdyne as a production test technician, but I was soon working with engineering, purchasing and the manufacturing engineering office on lots of special projects. I got a decent raise every year and managed to have a lot of changes implemented in the 30 year old company. At one time it took years to get an ECO on any product over a year old. By the time I was done pushing the right buttons, engineering had 72 hours to sign off an ECO, or have damn good reason to do it another way. I qualified new components and blacklisted some long time suppliers who denied there were any defects in the parts we received. I designed and built test fixtures, wrote test procedures and whatever else I had to do to make sure our product was top notch, and shipped early. Shipping "Right On Time" was a failure as far as I was concerned. I wanted to make sure it arrived a few days to a week early, just in case there was a problem with the shipping. The quicker a radio was through final test, the quicker it left the plant. Rather than make testing simpler, I added test to check for things that engineering had omitted. The better the board or module was when it left the module line, the less time it spent in final test. Hell, I even worked a very boring QA job at Cincinnati Electronics on the PRC77 backpack radio for a year doing module interchangability testing, and final testing on the SATE that was controlled by a four bit minicomputer.

He doesn't want a job, he just wants to whine and live off his wife's money as long as he can.

Its simple. You really want to work, and Bill's just too lazy to work 40 hours a week to find a paying job. Finding any job is a full time job, unless you don't really want to work. Until my health started failing I had only a couple times I really had to look for work, but it was a concerted effort to track down every lead that might pay off. So what if it wasn't the job I was looking for? Its a hell of a lot easier to get a job when you are already working somewhere else. That is one reason that I've worked in so many areas of Electronics. A job is a good job if it pays your bills and leaves you happy about your work at the end of every day. I started in TV repair while I was in Jr. High School but I was quickly bored with it, so I moved on. repairing two way radios, ham radio and even CB radios to learn more about RF. then it was on to broadcasting after I was drafted. Whatever came along, I was ready to tackle the job. I didn't brag about my education, or act like a pompous ass when applying for a job. I told them what I had done, and answered any questions that were asked. I usually jot the first or second job I applied for.

Like the old cliché: "If you really need something done, give the job to a busy man."

We were simulating a circuit where the restor was tied to the TTL output, which could be as low as 2.4V

k1 = ln 2.4V/2.0V = 1.2

The other extreme starts the ramp at 0.4V - the worst case low output voltage and pulls up to 5.0V

k2 = ln 4.6/(4.6V -0.4V) = 0.091

My numbers are 1.2/0.091 = 13.2

You've written ln (natual logarithms with base e ) but your numbers are log (logarithm with base ten) but it doesn't make any difference to the conclusion.

I first did this at EMI Central Research, where the junior engineers knew themselves to be an elite group. I wouldn't have got anywhere trying to browbeat them. The worst cases were barely realistic, whence the 10:1 claim, rather than 13:1.

I regret that I can't reconstruct the exact circuit that we were modelling

As with the 555, I came, I saw, I deprecated. Both are low-rent neighbourhoods.

I cut and pasted it into WordPad, saved it as a file called 555.cir and the latest version of LTSwitch rejected it with the error message "Multiple Instances of 'Symattr'".

Post a circuit diagram ...

Try saving it with .asc instead of .cir . It worked ok for me, and I just updated Switchercad this morning. Make sure to select new file: txt before creating the file or Wordpad will add lots of trash to the file. It saved as a 2861 byte file.

Save it as a .asc file like Michael Terrell suggested and it'll work fine.

Just as an aside, if it's important for the cap to be discharged quickly when the one-shot times out, there should be a diode across R1, with the cathode on the output of the gate. Unfortunately, it takes too long for the simulator to run the circuit with a diode (1N4148) in there, so I put a PNP in there instead and it runs fine.

Go figure...
