WebFeb 17, 2014 · 2 Answers Sorted by: 0 Try this: Let's say you are shifting by 3.5. Figure out what the oversampling value is (i.e. what value will change the shift into an integer - in this case it is 2). ov = 2; a = 3.5*ov; y = downsample (circshift (interp (s,2).', -a),ov); This still has some ringing at the edges, but much less than your sinc approach.
