Modifying gr_peak_detector

GNU Radio
1

Hello,

I’m working now with peak_detector block and find out that some
functions
don’t really work.
I’ve used the following 2 blocks:

  • Peak Detector (gr_peak_detector): the parameter “look ahead” seems
    have no
    function. I gave “look ahead” many values but the peak value did not
    change.
    I’ve seen in the gr_peak_detector_xx.cc that the variable d_look_ahead
    is
    called but it is not used in the main program.

  • Peak Detector 2 (gr_peak_detector2): in this block “look ahead” is
    used,
    but sometimes the peak detector freezes (output signal stops running in
    scope sink).

So I decided to use the first peak detector for my work, but I need also
the
look ahead function. Could anyone please help me in modifying the C++
code ?

best regards

Hello again,
I have modified a new cc code gr_peak_detector3_fb. But it was said
that:
'd_look_ahead_remaining’ was not declared in this scope. Can anyone
please
have a look at it ?
Thank you

Regards
