A plurality of contemporaneous orthogonal excitation signals (S1(t), S2 (t) . . . Sn(t)) are simultaneously driven onto the row conductors, respectively. The capacitively coupled signals on the column conductor may be influenced by a touch (10) on the capacitive touch screen. Receiver circuitry (50) includes a sense amplifier (21-1) coupled to generate an amplifier output signal (r1(t)) in response to signals capacitively coupled onto the column conductor. WHT-based circuitry (35) determines amounts of signal contribution capacitively coupled by each of the excitation signals, respectively, to the amplifier output signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Touch-sensitive interface and method using orthogonal signaling","description":"A touch screen system includes a capacitive touch screen (1) including a plurality of row conductors (7-1, 2 . . . n) and a column conductor (5-1).
