Hello,

I searched in this forum for adptive filtering which resulted in many related threads but thought to start with examples here

noisecancelexample

I aam getting this error "undefined variable "dsp" or class "dsp.LMfilter" when the example is used. I have signal processign toolbox but not DSP toolbox(i think).Can I know how to get DSP toolbox.BTW,I am using MATLAB7(R2008b).

Thanks.

You release don't have this newer feature. If you have access to Filter Design Toolbox and would like to use an LMS filter, you can try adaptfilt.lms

But I wonder if this adaptfilt.lms will work same as dsp.LMfilter for cancelling the signal as expalined in here in MAtlabexample1

Can I know how to use this adaptfilt.lms to cancel the signal noise because the Matlabexample2 of adaptfilt.lms shows its usage for system identification but not signal noise canellation.

If possible an example showing the usage of adaptfilt.lms to filter noise from signal.
