Abstract

In many applications transmission facilities having different impedance characteristics must be concatenated in order to establish a signal path between a signal transmitter and a signal receiver. Conventional impedance matching transformers are inexpensive and effective for matching the impedances of the various segments of the path. However, they will not pass direct current (DC) and, therefore, cannot be used to effectively pass digital signals which have substantial DC components.
