System and method for multiple object detection on a digitizer system

A digitizer controller comprising:

• a circuit associated with a digitizer sensor and configured to:
• transmit a query signal;
• sample first outputs from an antenna;
• demodulate information from the first outputs to identify an object;
• sample second outputs from the digitizer sensor that is separate from the antenna;
• identify an object interacting with the digitizer sensor based on the first outputs;
• determine a position of the object interacting with the digitizer sensor based on the second outputs;
• associate the position determined with the object identified;
• and
• provide position of the object and the identity of the object to a host computer.
