Yes, we already established that _you_ want the filter to do that. What
_Fred_ is saying (and, for that matter, I also) is

>>> What does the MATH say that a matched filter is designed for <<<

Because if you ain't applying a filter to the purpose for which it is
designed, and hoping that a high concentration of buzz-words will make
things operate well, then you ain't doing engineering -- you're doing
magic, and the next step is to go buy some live chickens to sacrifice.
