Re[Discuss-gnuradio] sampling precision

[irene159]

Hello,

I run into some weird results on the
rational_resampler.rational_resampler_ccf output. 

Look at picture 1 [1] bellow: 

     Signal input : Carrier of 1,4 Mhz sampled at 640 Ksamp/s
     Interporlation resampler = 2
     Decimation resampler = 3



Manual extract:
fractional_bw: fractional bandwidth in (0, 0.5), measured at final freq (use
0.4)
type fractional_bw: float

Can someone give me more informations on the "rational_bw" parameter?

Are there any files using resampling function that I can take a look at?
