title = "Causal approximations",
abstract = "The previous chapter considered the approximation of causal transfer functions in bases of the disk algebra in the form (7.1). There, it was important that the coefficients ηk = ck(f) depend only on the given function f which should be approximated, but not on the approximation degree N.",
