Abstract The problem of efficiently approximating real frequency data, which represents either measured information of a physical system or idealized curves to be realized by rational positive real (PR) or bounded real (BR) functions is considered. The final rational function is guaranteed in advance to satisfy the conditions of physical realizability. All the steps of approximation are executed in the real frequency domain. Illustrative, numerical examples are given.
