Claim 6:
7. The touch-sensitive apparatus of claim 6, wherein the control circuitry is configured to:
determine the resultant signal corresponding to the mutual capacitance between the first electrode and the at least one receiver electrode by subtracting the second, third and fourth measurements from the first measurement;
determine the resultant signal corresponding to the mutual capacitance between the second electrode and the at least one receiver electrode by subtracting the first, third and fourth measurements from the second measurement;
determine the resultant signal corresponding to the mutual capacitance between the third electrode and the at least one receiver electrode by subtracting the first, second and fourth measurements from the third measurement; and
determine the resultant signal corresponding to the mutual capacitance between the fourth electrode and the at least one receiver electrode by subtracting the first, second and third measurements from the fourth measurement.
