high Q eq or parametric

[qweetz]

hello : )

i am wondering if anyone has any experience with building an EQ module?

i am hoping to learn how to make a high Q ( narrow band) eq , i have some experience building from schematics.

this eq module will not be for music but for separating ( say a sine wave at 700hz from a mono signal that contains various other sine waves. they are control signals. so need to be separated for them to be of any use.

i can do this from a digtial parametric eq but that adds latency, so I hope for an analog solution. Perhaps boosting the desired sine wave with one eq and then with another eq cutting all around it so to separate it as much as possible?


thanks for any help you may offer.
