There are quite a few questions like:

  • What is the definition of ...?
  • What is the difference between ... and ...? (asking for definitions of the terms)

IMHO these are not DSP questions and should be flagged and closed because I consider these of very limited value and is basically the expression of "oh no, I don't know the difference and Google does not answer exactly... should I need to perform actual work by looking for individual definitions before plugging in my brain to figure out the differences or should I have someone doing it for me?".

But I am sure not everyone would agree with my view [1]. Until now, I directly asked the OPs to go and look for themselves and then to answer their own questions here.

So what do you think? Should we answer/ignore (depending on your view)? Should we flag to close? Should we encourage them to answer themselves? Anything else?

[1] Just to make things crystal clear: the little monologue is obviously ironic. I doubt that anyone asking for a comparison of available definitions would really think that deeply.

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 request is fine.

Moreover, it can be beneficial for other users. I know about nothing about communications, and I like to read details about concepts I am not aware of.
