Denominator Transfer_function_Denominator Transfer_function import gnuradio.input.Denominator gnuradio.input.Denominator.Denominator($num_inputs) Order of Transfer Function num_inputs 1 int in0 float 1+$num_inputs out float This will take the coefficient values for the Denominator. in00 = value of the coefficient of s^0 in01 = value of the coefficient of s^1 in02 = value of the coefficient of s^2 and so on..
