Abstract :
The problem of frequency weighted L∞ norm approximation is considered. The authors extend some results of Nehari (1957), Adamjan, Arov and Krein (1978), and Glover (1984) to the frequency weighted case. Explicit state-space solutions are obtained for all the weighted L∞ norm approximation problems that are considered
