ABSTRACT:
An electronic voting system includes a plurality of wireless response units, each response unit capable of transmitting several different digitally coded signals. Each of these digitally coded signals corresponds to the response of a person responding to a given stimulus. Each response unit transmits a selected digitally coded response via a radio frequency signal during one of a series of time intervals, a different time interval corresponding to each of the response units. An interrogating and response processing unit signals the response units to commence response transmission and receives, processes and displays the transmitted responses for observation by selected persons.
