decimation filter for sigma-delta

Started by Pavel Yermolenko September 9, 2001
Hello

I will be grateful to anyone who could help me to resolve the problem
concerned sample rate conversion. I have tried to simulate in Simulink
famous Hogenauer structure: integrator downsample differentiator.
But the results of simulations are different from ones of classical sinc
filter. May be there is an error in my model. I attached two files:
Hogenauer filter file fltr1.mdl, classical sinc filter file
fltr2.mdl.

Thank you in advance.

Pavel.
