[edit] Summary

This diagram illustrates the wrong and right way to build a two-wire repeater for telecommunications. In the upper diagram, the output of the upper amplifier would directly feed the input of the lower, creating a howling situation. In the lower diagram, hybrid coils are inserted, resulting in the correct amplification of both the west-to-east signal and the east-to-west signal.
