Coding error for web version

filtTx = dsp.FIRFilter('Structure', 'Direct form symmetric', ...
'Numerator', fnorm);
Why This coding show an error?

Hi Mollah,

I understand that you are trying to get a finite impulse response using dsp toolbox but getting some error.

I see that you are using Name Value pair "Structure" and "Numerator" along with the FIRFilter function.

According to the documentation 'Numerator' should be a row vector i.e just one row.

Assign 'fnorm' to a row vector and try running it again.

For more details go through the required documentation - FIRFilter

Please look into the below code for reference:

fnorm = [1 2]; % Making fnorm a row vector
filtTx = dsp.FIRFilter('Structure', 'Direct form symmetric', ...
'Numerator', fnorm) 

filtTx = 
  dsp.FIRFilter with properties:

            Structure: 'Direct form symmetric'
      NumeratorSource: 'Property'
            Numerator: [1 2]
    InitialConditions: 0

  Show all properties

Hope this helps!
