You can use it as a filter. Maybe, if you are doing a sampling rate
increase, you
need filter the upsampled signals for removing the images. However,
note that the filter
frequency response is not flat and may affect the pass band of the
signal.

You can read a nice article on CIC by Richard Lyons @

Also, I have tried to provide some small pieces of matlab code for cic
filter at
http://dsplog.blogspot.com/2007/07/example-of-cascaded-integrator-comb.html

Hope this helps.

Hey guys
I have to design cic interpolation filter using system generator.I am
trying to find any single application like in wireless area or in audio
signal.So can anyone please suggest me?
