  • Method of combining signals in a telephone conference circuit
    Patent number: 5212726
    Abstract: A method for combining signals for a telephone conference may include a multiplicity of identical adders for combining six signals and providing a single combined output. The adders may be arranged in a repeatable hierarchical scheme in which each group of six conference members includes an adder for combining all six signals, with the output of this adder being provided to other groups of six so that each conference member receives signals from every other conference member. As few as three hierarchical levels of addition may be used with up to 216 members. Adders may also be arranged so that a member of a first conference may monitor other conferences without affecting the first conference.
