Abstract :
A simple method for obtaining a stable reduced-order ( 
th-order) approximant 
for a stable hlgh-order ( 
th-order) transfer function 
is described. The method is an improvement over some previous methods [1], [2] in that it not only ensures matching of the first time moments of and , but it also ensures that the ( 
)th time moment of be as close as possible to the corresponding value in .
