i have a small doubt .. what do you mean by a estimate of a filter and estimate of a channel? And what is the use of modulation of a filter with a DFT or cosine etc? Please help me geeks. .
What do you mean by Estimate of a Secondary path?

Even today, it is not a compliment. We could probably provide more informative answers if you tell us in what context these questions arise.

(It still means "weirdo" to me, and I'm not nearly as old as you). I don't know what you'd call someone who bites heads off of chickens these days -- probably some elaborate euphemism for "completely nuts, off his rocker, hide your underage daughters (and sons!), etc.". -- www.wescottdesign.com

Like a stable hand, just not as malodorous.> I don't know what you'd call someone who bites heads off of chickens > these days -- probably some elaborate euphemism for "completely nuts, off > his rocker, hide your underage daughters (and sons!), etc.".There's a new word for it?

And DFT of which signal should i use here? My second question is, how can i implement this function in Z transform with matlab?

When we talk about geeks, we often picture somebody dribbling snot who's excessively enthusiastic about stuff like star wars etc.> There's a new word for it? > > Jerry, nerd and proud of it.Exactly! Often times the quite subtle differences between geeks and nerds are lost on the lay public. The most illuminating distinguisher IMHO is that nerds get the job done whereas geeks don't. All said, this is quite culture-dependent. For instance, I wouldn't mind being called _Otaku_. -Momo
