Hi all,
I am newbie to MATLAB. I was trying out this LMS filter MATLAB example, but gets the following error
"Unable to resolve the name dsp.FIRFilter."
signal = sin(2*pi*0.055*(0:1000-1)');
noise = randn(1000,1);
filt = dsp.FIRFilter;
filt.Numerator = fir1(11,0.4);
fnoise = filt(noise);
d = signal + fnoise;
Do we need to have separate licence to run the tutorial?
PS: Currently I have licenses for the following products,

Hi Veeresh,
The dsp.FIRFilter system object is part of the DSP System toolbox which is a separate licensed product. You can however try out the code using MATLAB online.
Note: Please check if you are eligible to access MATLAB online from this page.

Hi Uday,
Thanks for the response. I believe we need to have a license to try out the code on MATLAB online too. I receive the same kind of error over there.
