Introduction. Transfer functions process a time-varying signal – a proxy – to yield another signal of estimates ( Sachs, 1977). In dendroclimatology, the proxy is a tree-ring parameter, such as density or width, and the estimate a parameter of past climate, such as temperature or precipitation.Solved Responses of Systems. Using the denominator of the transfer function, we can use the power of s to determine the order of the system.. For example, in the given transfer function , the power of s is two in the denominator term, meaning that this system is a second-order system. Transfer function stability is solely determined by its denominator. The roots of a denominator are called poles. Poles located in the left half-plane are stable while poles located in the right half-plane are not stable. The reasoning is very simple: the Laplace operator "s", which is location in the Laplace domain, can be also written as:
