ABSTRACT:
A wireless communication apparatus sends X and Y coordinate position signals of a pen on a tablet using position modulation of three pulses, the time separation between the first and second pulses being proportional to the X position and the time spacing between the second and third pulses being proportional to the Y position. At a receiver, the three-pulse wireless signal is received and the X and Y coordinate information is determined therefrom.
