Inputs/Outputs

  • c1ddbl.png Numerator 1 —

    Numerator 1 contains the numerator polynomial coefficients, in ascending order of power, of the first rational polynomial G1.

  • c1ddbl.png Denominator 1 —

    Denominator 1 contains the denominator polynomial coefficients, in ascending order of power, of the first rational polynomial G1.

  • c1ddbl.png Numerator 2 —

    Numerator 2 contains the numerator polynomial coefficients, in ascending order of power, of the second rational polynomial G2.

  • c1ddbl.png Denominator 2 —

    Denominator 2 contains the denominator polynomial coefficients, in ascending order of power, of the second rational polynomial G2.

  • i1ddbl.png Numerator Out —

    Numerator Out returns the numerator polynomial coefficients, in ascending order of power, of the rational polynomial that results from the mathematical operation.

  • i1ddbl.png Denominator Out —

    Denominator Out returns the denominator polynomial coefficients, in ascending order of power, of the rational polynomial that results from the mathematical operation.

  • ii32.png error —

    error returns any error or warning from the VI. You can wire error to the Error Cluster From Error Code VI to convert the error code or warning into an error cluster.

    • The following equation defines the negative feedback equation.

    where G1 and G2 are rational polynomials, G1 = N1/D1, and G2 = N2/D2.
