Oh wow, the AD936x series was impressive for its I/Q calibration. Still is I guess, because there's been no compelling alternative even a decade later.
As I mostly deal with single channel applications, I get to use double superhet and avoid runtime calibration. Not an option here, Zero-IF has too much in the Pros column for multichannel.
Yeah, jitter doesn't matter too much at low frequency IF. I/Q calibration is more likely to be the bottleneck. That and close-in spurs from the fractional PLLs.
I have very little experience with MIMO / phased-arrays, this application likely doesn't need ultra high SFDR.
The really intriguing part is the "Custom ADC" here, seems like some kind of 1-bit ΣΔ oversampling ADC (704 MSPS?). Single differential transistor, and captured by FPGAs LVDS RX.
Neat way to reduce cost and pin-count? But I think the typical FPGA clock tree has poor jitter performance. Not using the internal PLL(s) might help with spurs but the clock buffers are unavoidable.
The documentation mentions it's likely further degraded by noise from switching regulators. Oh the joys of hunting RF noise sources.
Only if the difference in signal power is high (>40 dB). It’s like saying collisions aren’t a problem in situations where no collision actually occurs.
Wish the proponents of stricter immigration would push for a proper national ID first.
Right now you have all the cons anyway, with none of the pros. A stitched-up database that has no laws attached to prevent its misuse. Just like with gun control, law enforcement could've made their job easier decades ago.
For the established players, it's the battery supply chain that's the main issue. Rest can be locally-sourced or manufactured. Makes them very nervous, having to import when tariffs and rules change everyday.
My city in South India could be an outlier but I see green EV number plates everywhere. Would love to see a state-wise breakdown for sale share.
The explanation is that the trusted brands (in 2Ws) are just now rolling-out EVs, the market is very conservative and home charging likely isn't an option if one's renting.
The cheaper variants now have enough range to relieve (urban) range anxiety, wasn't the case a year or two ago. My own model that's 4 years old, the new variant now has 2.5x range, faster charging and much better features. All that for the same price, and without any of the subsidies that used to exist.
These things take time, this is a low-margin business that isn't drowning in VC money.
It's the opposite IME, most petrol two-wheelers are massive money sinks past 5 years of ownership. You will likely spend close to original price in maintenance and repairs, with most models developing "unfixable" issues that massively degrade the experience. It doesn't need to be engine related for the costs to add up.
Even if the battery craps out after 5 years (extremely unlikely), it's a wash. That's before considering the fuel savings. Battery degradation is a bit of a meme, we aren't even 10 years into mass adoption of EVs for this to be a common experience.
Leasing land for solar pays very little. The only reason people do it is because the land has no better use and solar doesn’t permanently damage it the way mining or farming could. Other industries aren’t being priced out.
Talking more about some unrelated function taking down the whole system, not advocating for "offline" credit card transactions (is this even a thing these days?). Ex: If the transaction needs to be logged somewhere, it can be built to sync whenever possible rather than blocking all transactions if the central service is down.
Payment processor being down is payment processor being down.
It's "legal" at first glance but it's effectively banned in most cases. No monetary compensation, only direct relatives, only traditional pregnancy, etc.
It's outright banned (commercial) in most of EU. In most countries it was left unregulated for a long time but most of them are choosing to ban all commercial forms of it. Besides US, most major countries have banned it.
Now many people do ignore these laws and most governments do little to enforce them unless they make the news for some reason. Banning commercial forms of it just ensures abuse and issues go unreported. It's the paternalistic part of feminism that's been leading the charge for modern bans, with both liberal and conservative roots.
Having kids is half the reason (or more) for such marriages, nothing completes the nuclear family picture quite like it. And not like it's easy for gay couples in accepting environments to have kids either, surrogacy is banned in most countries ("liberal" ones too, US is kind of an exception here) and adoption is nigh impossible. Some countries like Italy go as far as selectively making both illegal, but only for gay couples.
I would say many asian parents care very little about the partner, as long as they get their grandkids. A mix of that and "what would society think".
I'm guessing India, and it's dowry part of it that complicates things a lot. And once either party goes into legal proceedings, it becomes a shit slinging mess of he-said she-said. Hence why most people try to "settle" things out of the court even if they were the victim. You wouldn't wish the Indian legal system on your worst enemy.
The "omg centralized infra" cries after every such event kind of misses the point. Hosting with smaller companies (shared, vps, dedi, colo whatever) will likely result in far worse downtimes, individually.
Ofc the bigger perception issue here is many services going out at the same time, but why would (most) providers care if their annual downtime does or doesn't coincide with others? Their overall reliability is no better or worse had only their service gone down.
All of this can change ofc if this becomes a regular thing, the absolute hours of downtime does matter.
People who don't need that, also don't care much for an hour or two of service disruption. Most users will have far worse disruptions with the alternatives.
