Hello, A couple years ago I was working with GNURadio and noticed that the filtering weights for the Preemphasis Filter used in FM transmission had not been implemented. I submitted some code at that time. I was browsing the source and found that it's still listed as a "FIXME"
http://gnuradio.org/trac/browser/gnuradio/trunk/gnuradio- core/src/python/gnuradio/blksimpl/fm_emph.py The preemphasis filter should be the inverse of the deemphasis filter, so copying the deemphasis code and swapping the Ataps for the Btaps should implement it. I did this previously and it worked well. If there's anyone who's actively working on the code that could update this, I'd appreciate it.
