I am working on the following version of matlab and SPT
MATLAB Version 7.14 (R2012a)
Signal Processing Toolbox Version 6.17 (R2012a)
From looking at the web I understand that the signal processing toolbox should include the comb filter and notch filter under fdesign. This is not the case in my version.
What is the problem?

Figured it out, I had the wrong toolbox. Apperently I do not have DSP system toolbox, only signal processing toolbox.

or You can just type help iirnotch and then see the following example:
% Design a filter with a Q-factor of Q=35 to remove a 60 Hz tone from % system running at 300 Hz. Wo = 60/(300/2); BW = Wo/35; [b,a] = iirnotch(Wo,BW); if you replace the 60 with 50 Hz and then do: Y = filter(b,a,X)

This doesn't work if you don't have DSP toolbox, since it doesn't recognize "iirnotch" function.
