The synthesis process is essentially a Darlington approach, requiring to construct the input and output admittances to evaluate the elements of the network.
The results indicate that the atmospheric gravity admittances are reduced with the increase of the signal frequency and may contain the inverse barometric effect.
The concept oi R-type function and it's construction rules are presented. The general method solving the parameters of the open-circuit impedances or short-circuit admittances is also given.
