interpolation and decimation FIR filtering

Question asked by kaushalkumar on Feb 4, 2013

my requirements are like this:


i have an input buffer taking data from file "input_14.dat" of 14 sampler which is to be interpolated by a factor of 5 resulting in 70 samples and this is to be further decimated by a factor of 3 resulting in roughly 24 samples. i am able to perform the required multirate filtering but there is a problem of phase shift in the final output which is to come from the decimator output.


can anybody shed some light on this issue as soon as possible.

i am attaching the code for your kind reference.
