You can convert to quadrature by either sampling a signal at >= 2 * Nyquist and using the Hilbert transform, or using two ADCs 90 degrees out of phase. When you run two ADCs 90 degrees out of phase that introduces another source of error

Small and big are relative descriptions, not absolute. Jiangsu province is small compared to the major Chinese metropolitan areas. Comparing cities to world regions is rarely done. Also I think many people would say Birmingham, England is s

Things I never liked - spending hours debugging WINE issues or browsing the wine compatibility website trying to get things to work to play a video game, which I'm already using to get away from doing tedious work.

Most students do not have a normal high-school graduation exam. Neither is there a national US school curriculum. Therefore, it is difficult to compare GPAs between students from different school systems. The SAT is also a thinly disguised

I can't speculate on what's actually on US Navy warships right now, but I'm telling you commercially you can distinguish birds from drones under a kilometer away today. The knowledge has been around on how to do so with radar

I think one thing the US does well is provide education and support for mentally disabled children, and children from foreign countries who need remedial ESL instruction. To speak in generalities, in many schools it makes up ~25% of personn

I feel attacked. I'm a DSP engineer and I haven't implemented an analog filter since I graduated. If we got into detail on RC filter gain and phase shift I'd fail. Do I have to give my EE degree back?

If it's just circuit design, the difference between an EE and a physicist is 6-9 credit hours of courses. You will both share all the necessary prerequisites in mathematics (mostly Fourier analysis, linear algebra, basic statistics, an

AWS style small payments existed at coin-operated arcades. They're all dead, Jim. Micropayment news services have existed (Blendle). Unpopular. Pay-as-you-go prepaid cell phone service is also niche. So is the a-la-carte gym membership

My friends who work at Google do not have such a workweek. Aren't you exaggerating a bit? At the very least, don't pass it off as universal.

1) If you are a US-born citizen and qualify for a security clearance, jobs aren't as scarce as you think. 2) You are right the pay is worse in the public / government side. I will say - you might not believe me now, but it really

I have the same experience; I think what school you get to attend is just the happy byproduct arising from your internal combination of intelligence, self-motivation, and emotional resilience (mostly! I am speaking in generalities). I remem

That's an interesting question: how much would it cost to keep 3 years of food (let's assume the bare minimum - refined white flour) in reserve for the entire United States? What is the cost of food subsidies over the same period?

The one thing about Pluto that turned me off is that when you export to PDF it puts an advertisement in the header and footer for Pluto. It was embarrassing to send my work to non-technical people.

You're exaggerating a little but I agree. I think your example with the FD map binder is a little weird though because that is the one thing that is worse than a maps app with real-time traffic updates. That's a killer feature esp

Give up on your dreams, your undergraduate GPA needs work. Your best bet is to work somewhere prominent as an AI/ML engineer and move over later to research, after you have practical experience in the field.

Students don't avoid it because analog is black magic, they avoid it because there's only a handful of places you can work at with that skill set. In the United States, today, an RF design engineer's job prospects are mostly
