Abstract

A low cost x-y digitising system is described for use in consumer electronic devices, such as portable digital assistants (1), mobile telephones, web browsers and the like. The digitiser includes a resonant stylus (5), an excitation winding (29) for energising the resonant stylus (5) and a set of sensor windings (31, 33, 35, 37) for sensing the signal generated by the stylus (15), from which the x-y position of the stylus (5) is determined. A novel stylus design is described together with novel digitiser windings (25, 31, 33, 35, 37) and novel excitation and processing circuitry.
