FLEXIBLE REPEATER DESIGN 75 builds out the leakage inductance of the transformer and together withcapacitor Cs controls the shaping at the top end of the band. These ele-ments are adjusted during manufacture of the networks to provide thedesired shaping. The equivalent circuit is an approximation to the true transformercircuit. By standard network analysis techniques the ratio V/Ei, thegain of the network, can be obtained. The agreement between measure-ments and computation is sufficiently close, several hundredths of a db,to insure that the representation is good. Each coupling network is designed to provide approx
