Abstract
A touch screen system includes a capacitive touch screen () including a plurality of row conductors (-) and a column conductor (-). A plurality of contemporaneous orthogonal excitation signals (S(t), S(t) . . . S(t)) are simultaneously driven onto the row conductors, respectively. The capacitively coupled signals on the column conductor may be influenced by a touch () on the capacitive touch screen. Receiver circuitry () includes a sense amplifier (-) coupled to generate an amplifier output signal (r(t)) in response to signals capacitively coupled onto the column conductor. WHT-based circuitry () determines amounts of signal contribution capacitively coupled by each of the excitation signals, respectively, to the amplifier output signal.
