Coupling coefficients of ladder networks with maximally flat amplitude responset

The problem solved in the present paper is that of expressing the coupling coefficients of a ladder network with maximally flat amplitude response in terms of the dissipations of the input and output branches. Green has already found one set of values; the present paper gives the generalized theory of Green´s method of solution, and shows how to obtain all sets of values. These are given for networks containing up to five branches, together with the values of dissipation for which they are valid.
