Im a HW engineer and don't really understand "complexity" as far as this article describes it. I didn't read it in depth but it doesn't really give any good examples with specifics. Can someone give a detailed examp

The observation of the Hubble constant requires us to measure distance to an object in space. This is very hard to do at the extreme distances required ( https://en.wikipedia.org/wiki/Parallax ). In the end, the variatio

All definitions of entropy stem from one central, universal definition: Entropy is the amount of energy unable to be used for useful work. Or better put grammatically: entropy describes the effect that not all energy consumed can be used fo

"....why doesn't that throw in every EDA tool?" This would require repetitive SPICE simulations, or basic rule checking at the very least. Nobody does full SPICE simulations at the board level however basic input/output

I work in analog, 1) Noise is an issue as the system gets complex. You can't get away with counting to 1 anymore, all those levels in between matter. 2) Its hard to make an analog computer reconfigurable. 3) Analog computers exist c

You're never going to find a solid answer to these questions. The best you can do is ask yourself "does this seem reasonable".

Bandpass sampling is a regular technique used in the RF world to mix down a signal to its final IF or baseband frequency, digitally. In this case, you are undersampling but using a well defined signal that you have apriori knowledge of wher

"Those resources don't come out of nowhere, so there is a need for immigration as well to get work done." Efficiency gains in a process certainly create extra "resources" whatever they might be. But I do applaud you

Almost every person that has told me about the perils of overpopulation...more people, has also told me that its in my best interest have open borders e.g. more people. Why the hypocrisy in message? The unbelievable immigration in my countr

Why does everyone support wall streets "increase GDP at all costs" immigration platform? It seems to be astroturfed alot. Pay a country's people more so that they have more time/resources to dedicate to making a family.

I clicked on the link thinking it was about parasitic extraction and capacitance tables; referred to as "cap tables" in industry for circuit design. I was very disappointed.

I did not read the article in-depth but class D audio amplifiers use variable pulse widths and then filter it before the speaker. Aside from very good efficiency you also remove the need for a transformer using this method hence why its use

Your fellow canadian VE7KFM is one of the worst offenders: https://ve7kfm.com/profiles.html I've been yelled at by him before on 14.275, about 15 years ago. He's still at it.

Yes, but has a major purchaser of spectrum complained? No, because its CB and they're not interfering with AM/FM broadcast, first responders, aviation or cellular bands. Therefore, nothing will get done and I doubt the FCC is even

Everyone is saying "survivorship bias" but I don't think its that easy. How is survivorship biased by reparability? Is the widget still considered more durable if it breaks but can be fixed? I would say so.

" full stack rf role" This is the right idea, in many cases, the "HW" team might focus on RF but does "antennas to bits" (i hate that term) because of the need to get a prototype up and running to test it. If y

You really are proving my point. Based on your misuse of nomenclature its obvious you're not a HW guy. The ADC is the last in an RF chain and typically sets the systems dynamic range if you've done things right. There is nothing s

As I said, nature is analog, it will never go away. Interesting areas of analog research are in things such as switched capacitor architectures where you can filter as close to the antenna as possible, reducing the impact of an interferer o

Yes. Many analog design groups in college went from 10's of students 10-15 years ago to just a few now, not due to lack of funding but due to a lack of interest. Our interface to nature is through analog signals but due to the heavy re

Yes all correct, you didn't capture any of the tradeoffs but thats the basic idea.

by mwbajor 3y ago
Yes. But if you really want to get into it you need to do it. You could make some cheap PCBs and measure them with a cheap network analyzer. RF design has never been more accessible. The books will get you started and you will start to thi

Not only that, but it also stems from "management" or "customers" unable to contemplate tradeoffs in the design. The reason FPGAs and RFSOCs are pushed so much in certain industries (we all know which one) is because the

"I don't get why only men are making this decision though." Oh come on, we all know why. Its socially acceptable to hate men and blame them for everything bad. It starts or feeds negative emotions.

What got me into analog computing was eliminating the step (data conversion) between sensing the signal and doing something with it. But when you add in the inflexibility of analog circuits, the mostly analog solution is almost always the b
