Hi Nikos

Roughly speaking, the old atan demod, would load my cpu(3ghz core 2 duo) on approx 8.5%, with the new
modulator the load would be ~5%

There is a little penalty however, it seems that my demodulator is a little more noise sensitive, but it is not much.

Great! Performance is always welcome;-)

Do you have any benchmarks?

Hi and thanks for a great tool set.

I've implemented a faster FM demodulator for rlt_fm. Its an instantaneous frequency demodulator, like the already implemented atan method, but it uses some math tricks to get rid of the the actual atan calculation. Feel free to use it if you wish

Best regards
