- Create a "Discrete Transfer Fcn" block.
- Double click the block and navigate to the block's properties.
- The length of the "numerator" and "denominator" vectors in the "Data" section of the "Main" determines the order of transfer function block.
- To obtain a 4th order transfer functiton block, set numerator and denominator to a five-length vector.
- The order of the denominator must be greater than or equal to the order of the numerator.
