Hi


There are amny commnds in ML for FIR lp filter design. If its
descrete kind, use commands filter, fitfilt etc. You want the shape
of filter to be gausian, for that you take inverse fourier of the TF
of lp filter , convolve it with a gaussian signal in time domain,
which shall give you desired one.


hope it helps

Hi thanks abhay


Well i understand what u said but it would be help me more if u can
give me code of what u wrote .Thanks


If u can help me with same thing done using simulink block then it
would greatly cler my work


thanks

if you want using simulink, see FDAtool


Moreover, show us what you did so far, i.e your code, etc. we can
help you in fixing bugs
