[Discuss-gnuradio] help for peak detector

[Markus Feldmann]

Hi All,

i want to build a peak detektor with a Usrp(LFRX),so i hope some of
you can give me some hints about the peak detector modules ?

As i know, there are 3 peak detector:
1. Detect Peak
2. Peak Detector
3. Peak Detector2

Therefore i have some questions:
To 2.) What allowed values for <Look Ahead> ?
       And what does this mean ? Which unit ?
       What is Alpha, and which are allowed values ?
       If the peak detector gets a peak, what does it spit
       out ?
       Which are the allowed values for <TH Factor Rise/Fall>,
       is this in db or a linear factor ?

Is there any example for a peak detector ?
Is there also a peak detector with a complex input ?

Regards Markus
