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 example of what the author is really talking about?
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 variation in the Hubble constant might be only due to our limited accuracy in measurement.
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 for work.
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 port checking (usually in the ERC check) does get performed. Even with RF designs, you carve out the piece you need to examine or design and simulate that. For the chips I've worked on, the full chip would get a SPICE simulation that would take days/weeks but this was for more R+D oriented mixed signal designs. I guess what I'm saying is the simulation of a circuit is best performed as a deliberate, iterative step in the circuit design process.
When it comes to layout however, you do get hints from the DRC checking tool (Design Rule Constraints) that will tell you if your trace is drawn incorrectly based on the DRC constraints and nowadays sometimes from an EM simulation that can be run in the background.
Completely automated design especially for analog will most likely never be a thing for the other reasons you list. However, I already can use "known good" circuits and modularize them for reuse which does speed things up. This is critical in the ASIC world due to the large hierarchies in the design. Modular reuse is also a growing tool in the PCB world. Cadence now has a very nice module/reuse tool that can even detect and create modules to prevent you from having to redraw the layout for a sub-circuit multiple times if its not instantiated as a module already. I always like when more people want to get involved in HW, but what the OP is showing largely exists in the form of TCL and SKILL scripts in current EDA SW packages.
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 commercially believe it or not, but for niche applications and essentially as coprocessors.
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 where it is before and after sampling.
"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 for not saying "we need immigration because we need ethnic food" like most people say nowadays.
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 country is causing a reduction in quality of living not unlike what I would expect with overpopulation because.... it is overpopulation.
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. Even better, incentivize families. Or is that too expensive for bankers?
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 used.
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 monitoring it.
