Amrutha,

you should explicit your post.

What is the error message ? (we can't guess it).

Usually, in simulink, you just use a scope block to observe a signal

i tried connecting the output of digital filter to vector scope.But then error displays as "Error reported by S-function 'sdspsigattrib' in '/Digital Filter Design1/Check Signal Attributes/Check Signal Attributes': Input must be floating-point. my input to the filter is an analog to digital converted signal.Please help me sort out this problem..

you have a problem with the data types. use a block convert to observe your data (you may need to specify the ouput data type of this block).
