Abstract

A quadrature coder for a two-wire digital loop communication system is described in which data is sampled and quadrature encoded by being divided into two bit streams, one of which comprises every other bit in the original bit stream and the other one comprises the remaining bits. One of the divided bit streams is delayed by 90.degree. from the other. The delayed and undelayed bit streams are then recombined and transmitted over a two-wire loop.
