[Discuss-gnuradio] Rational resampler

[Marcus Leech]

I'm trying to re-sample signals, ranging from 0.5Hz up to about 40Hz, 
sampling them at some small
 integer multiple of their frequency.   Simple decimation isn't getting 
close enough, in many circumstances,
 leaving a significant phase erorr.

I'm thinking that I can get closer using the rational resampler block, 
but I need more guidance than the
 online documentation can give me.  Any clues?

My input sampling rate is from the audio card--16Khz to 48Khz.  My 
output sampling rate should be
 a small multiple (16 or 32) of the desired pulse frequency (0.5Hz to 
40Hz, depending on which object
 I'm trying to observe).
