I'm trying to test the notch filter code referenced here,
F0 = 60; % interference is at 60 Hz
Fs = 3000; % sampling frequency is 3000 Hz
notchspec = fdesign.notch('N,F0,Q',2,F0,10,Fs);
notchfilt = design(notchspec,'SystemObject',true);
I have the Signal Processing Toolbox but I'm getting the error below.
Unable to resolve the name fdesign.notch.
Signal Processing Toolbox Version 8.5 (R2020b)

The fdesign.notch function is in the DSP System Toolbox.
An appropriate Signal Processing Toolbox equivalent function is bandstop.
