Re: How can I split a periodic signal?

[Mike Markowski]

James,

I find an easy approach is to write the signal out as alternating i/q 
binary if it's not already.  That can be read into audacity as stereo 
(File -> Import -> Raw), edited and written back out as raw data without 
header (File -> Export -> Export Multiple, and choose Raw Headerless). 
Don't worry about audacity's sample rate because you're editing raw i/q 
anyway.  This allows editing down to the sample level.

Good luck!
