Reg. AGC3 in gnuradio

Can someone give me detailed information about the new agc (agc3) in
gnuradio?.Also is that agc a log mag. loop which is normally used in the
modern receivers?If there is a block diagram of the new agc3 then it
would
also help. Thanks ahead.

Hi Vamshi,
a quick look into the GNU Radio Doxygen
(http://gnuradio.org/doc/doxygen/group__level__controllers__blk.html)
reveals that there is no indication of logarithmics. I guess there is no
block diagram available, though.
Also, please refer to the rather well documented source code, the file
is part of your GNU Radio distribution (and on gnuradio.org and github)
under gr-analog/lib/agc3_cc_impl.cc .
Since I don’t know how familiar you are with the principles of coding
blocks: The relevant part is in the work() method.

Greetings,
Marcus
