Difference in the output of CIC decimator while using with unbuffer and without unbuffer

4 views (last 30 days)
I am using a CIC decimator block to downsample a high sample rate signal . the CIC decimator output is quite diffrent when i use it without unbuffer. but as for the FPGA apllication i need to unbuffer data the output is changed what could be the possible reason for this ? and how it could be resolved

Could you please provide a model that shows this behavior (you may want to try it using a fixed known input first)?
Are you sending in the input as a Mx1 array (sending it in as a 1xN array will have the block interpret it as multi-channel data).
