An interesting point when using Op-Amps: doing linear operations (addition/subtraction/multiplication by a scalar/integration/etc) is pretty easy (they are "linear devices"). Doing multiplication/division&

Are there any examples of these kinds of adversarial patterns that don't look like noise? While it is pretty easy to add noise to another image, it isn't exactly easy to do it to a real object. The noise wouldn't remain the

Because all the adversarial images that are out there look like noise. If you are training each image with a different amount of noise on top of it, then plausibly you could train the classifier to be insensitive to noise like this overlai

Part of the problem is probably that there is no money in it: Congressional offices don't have a big enough budget for the staff they need, much less any pieces of software/services.

I think the great shame is that many educators don't know about future career prospects in their profession.

The value-add of the mac store is just not very good anymore. There are only three reasons people might buy something from the mac store vs. from the developer directly: 1. To keep it getting updates through the app store vs. having to dow

Framed in that way, it is likely that running some sort of optimization algorithm is going to be tricky... Framed the way solitons are usually framed, as a waveform that doesn't change shape when propagated, it seems one could frame a

It sometimes surprises me what can be found here. Solitons are interesting, I have always been curious if anyone has done any sort of genetic search for solitons for more general wave equations. There are only a couple of known analytic so

2n7000, BS270 are both pretty cheap for small signal FET applications. For analog applications, BJTs are still very much important, but for digital stuff (and especially power stuff), it is usually easier to grab a cheap FET than use a BJT.

The first version references them to allow for a single point of refactoring to increase the number of command messages or status messages (the valid_xxxx_message() function call). He recognizes this as a not ideal and then refactors the c

I guess my point was more along the lines of: "Is that schematic really a good schematic, and if not, should it be the goal of a project like this?" Though I get your point as well.

Those schematics though are just throwing everything into a bus... It isn't really differentiating signals at all. What is the difference between just labeling all the FPGA outputs (which is done here), and then labeling the inputs whe

I'm a little curious... why? It is much harder to visualize, I don't think it is appreciably shorter to write, it isn't necessarily clearer. I suppose you can do interesting things like parameterizing parts on the value of ot

Do they actually sample the baseband digitally? I would expect that they are looking at the return as an amplitude modulated and phase-shifted signal at the carrier frequency. They remove the carrier frequency and then look at the (much sl

I think you are missing the point. A 10MHz transducer will be resonant at 10MHz. If you drive it with a square wave at 10MHz, it will naturally respond best at frequencies that are 10MHz, and will very poorly respond to frequencies that ar

Honestly, you aren't the problem. The problem is speculative investors who are buying lots of property in nice areas and sitting on them: not renting them, not living in them, but just letting them sit vacant. For a city like Vancouve
