Info needed.

[xmat]

Hello.

I am trying to find info on "transconductor comparators" to build a "analog adaptive weighted median filter"..
The filter shall be used for filtering impulsive noise from audio and video signals, and needs to be analog..

Any clues for references??

Thanks in advance,

xmat.

Sorry, bad way to answer a question...I have to rephrase it.

Any references on a device (IC) that does such a job??
Maybe some application hints??

Cause I 've already read the pdf you mentioned and it is a bit general...(not too many maths...heh heh)

Thanks in advance,

xmat.
