Good for RF sims. It's free compared to ADS which is NOT. You can use LTSPICE for some kinds of e.g. transmission line models but it doesn't have things like the Smith chart built in. You also can use Qucs for modeling things

Oof. There isn't room to just go to work... to work? I want to go to the office and interact with people who are the best at what they do, I want my company to hire those people, and I expect them to hold me to equal standards. When th

If you're going to create a new ARPA, don't forget to put strict limits on the tenure of your PMs, and high expectations on the outcomes of their projects. This will ensure the usual DARPA program has unreasonable and unachievable

I believe GP was suggesting that making a decision should be mandatory at some point. While I personally prefer the default here be to opt in as a donor, GP suggested merely that a decision as to yes or no should be required. Where I live,

I have trouble putting my finger on exactly why this feels wrong, but to me, the idea of buying a car - buying anything that has hardware in it that I have to pay extra to activate, it just seems wrong. I suppose it's the sense of wast

It had never occurred to me to wait for a class to teach me something. Just go out and learn it! If there are no references (books, wiki, blog, training resources) it's great fun to go your own way and figure it out from scratch. Usual

I was forced to try the referenced Bates method for several years as a child, spending about a half hour a day on it. The experience was not good and the effort would have been much better spent on academics or even sports. After several ye

It's probably about time this happened, but it is unlikely to occur as an amendment. The least populous states would instantly lose even the minimal power they have, and it would disadvantage the party of the rural, until such time as

Most of what embedded is, is hardware. To build the low level software and drivers requires a detailed understanding of the hardware and its datasheets. It would be pretty hard to give a generic overview of the software side these days, bec

Huh. I've been using Keepass2 with a smartcard for a long time now. I don't like that all passwords are unlocked at once, but the DPG approach seems to act the same way. The DPG approach also requires that if I update my 'ama

I think you'd be surprised. Despite the ease of obtaining an EMT license in states in the US, it is relatively difficult to hire them [at the wage the market wants to pay, which is near minimum for commercial services]. You'd like

Such a chip would enable the phone to act as a base station for a wireless headset. Snom make several varieties of such headsets. It is not necessarily proof of a "bug," could just be additional, perhaps never implemented, functio

Metal hydrides have been proposed as a possible solution. We talked to a small R&D firm years ago that had proposed putting power stations in remote areas where energy is immediately converted into a metal hydride; in their case, magnes

I'm the opposite of a biology expert, but from what I've read, the "miscellaneous non-vaccine compounds" in the solution are adjuvants which make the vaccine more effective by provoking the immune system into a response.

I read this article expecting to hear about potential liability concerns, not IP protection. It seems to me that I remember playing with a toy quite like theirs as a child many years ago. Basically cheap poker chips with cuts around the edg

The way you wrote that, doesn't make sense. The idea behind ANC is that you have some signal, sin(wt+p) from ambient noise, and to it you add -sin(wt+p). The sum of these is zero. You perceive it as silence because it is: you have adde

This is a trade magazine for people who assemble systems from components. So they put a router in a box, or whatever, and need a power supply and amplifier and connectors to the outside world. The finished system needs to pass compliance te

I do know how computers work, at the transistor level. But it boggles the mind to try to understand how a computer works from the transistor level to the point of where your mouse icon traverses across the screen. Trying to understand it at

I'd be interested to see the results broken out by racial group. There is evidence that blacks do not metabolize vitamin D the same way that whites do, and the standard test for vitamin D concentration does not measure its bioavailabil

So honestly, this demonstrates the value of an education in the field. The EE BS degree has a tremendous focus on theory and students don't really get a great appreciation for the reason that it has such a focus. But if you thought abo

I'm a working parent but I understand the frustration. People see from their own point of view. What non parents see is that I am no longer pulling the same weight I pulled last year. Someone has to pick up the slack or the schedule ha

No. I'll take an opposing viewpoint. It's not "really" valuable, it's marginally valuable. If your articles aren't yahoo-style clickbait, anything you'd do with that data would just make your future articl

Authors propose to mess with circuit board runs by adding components and modifying connections. There is no security on the design files, so they are trivially modified, though it is annoying to do so if you don't have the original des

Interesting article. Feynman had a story in one of his books (reprinted here: http://calteches.library.caltech.edu/607/2/Feynman.pdf ) in which he described running up and down stairs to see if it affected his abi

I agree that is how it works presently in the US. Nonetheless, parent's comment is interesting to consider. Why is it that way? Why don't Subaru etc just set a price, you buy the car, and be done with it? The answer is either that

We do the same thing. Keep is superior to a written list - you can organize it, so apples don't end up near the top of the list, and oranges at the bottom, and you end up walking back and forth through the store. You can have sub-items

In my opinion breadboards can't die soon enough. Too many new engineers think they can use them for prototyping circuits where the parasitic of the breadboard make it entirely unsuitable. Low noise amplifiers, high speed designs, switc

Well, it's absolutely not weird. Capacitors are happy to change current instantaneously but not voltage. It's in their spec: i=CdV/dt. If you charge a capacitor to a particular voltage, and then disconnect the capacitor entir
