  • Patent number: 3950618
    Abstract: An AC burst having a length depending upon the response chosen by the participant is put on a telephone line regardless of the operating state thereof, at a frequency outside of the telephone band. At the central telephone station the bursts are decoded and response signals corresponding to each answer are summed. The resulting totals are transmitted via private lines to a central computing station where the totals corresponding to a given answer are again added. For television channel polling, a control signal signifying an operative television receiver is also put on the telephone line and, at the central computing station computer circuits compute the percentage of television sets tuned to any given channel.
