Create a dsp.Differentiator System object with default properties. 

DF = dsp.Differentiator;

Use getFilter to get the underlying FIR filter, filter, which implements the differentiator, DF.

filter = getFilter(DF)
filter = 
  dsp.FIRFilter with properties:

            Structure: 'Direct form'
      NumeratorSource: 'Property'
