I suggest it could be educational, sometimes, not to edit it, but to ask the OP to fix it him/herself. And at least, Matlab has dftmtx.

Question about physical applicability of noise models are quite appropriate here. Indeed, no actual signal or noise realization can be perfectly modeled by a particular distribution, for several rea …

Sometimes, definitions varying among sources, and differences are not obvious, or misleading. As long as the OP provides clear references, and shows he did some work understanding, I believe the reque …

I fully agree with your response. Should the behavior happen again, an action on the author's account could be deserved.

As a relatively new member, I still find interesting that old questions pop up. This can be an incentive for answering, especially for newcomers. I do understand however this could be annoying. There …

With a background on audio, you can try geophysics. Oil price in not so high. Yet geophysics is slowly beginning to think "big data science", with tons of data to deal with.

Part of the problem resides in the culture of downvoting. Oddly, such cultural behaviors are quite different across different SE sites. Even if one does not understand a short answer, I see no reaso …

How to build a median filter function in 1D can be quite legitimate: nature of the samples (from few bits to double-float), off-line or on-line, $\mathcal{O}(1)$ and constant-time algorithms, using pr …

SE.DSP is peer reviewed to some extend. Not in the traditional "journal" sense, meanwhile predatory publishing or randomized peer-review, to name a few, have changed the deal. A post in SE.DSP can som …

The sole IEEE student membership cost about 30$, and the discount on conference fees is generally higher than this amount. The savings can even increase if you are a member of the society the conferen …

Work, work, and work. And fun, fun and fun. Fun can lever a lot of difficulties. The need for some math skills is a common repellant in signal/image processing. Yet, it is fun, because you can see res …

I agree with @PeterK. I'll add that answering questions is for me as well a way to order my thoughts, or to elaborate one a novel topic. So elaborate as much as you feel for the OP, or/and as much as …

This person is either very young ("never... in my whole life") or has never met a mirror. Let Darwinian selection do its job.

https://stats.stackexchange.com/ apparently kept the base url stats, while named Cross Validated. dsp is widely indexed, I would not modify it. Since the "name change is a one-time thing", I'd sug …

I am a living proof (so far so good) of the capture of one realization of the top user swag process. Still trying to infer the probability density function of this process on one sample: I am not a Ba …
