摘要： The touch-sensitive apparatus includes a touch sensing area, an analog-to-digital converter and a mixer. The touch sensing area has sensing pixels for receiving a touching signal to generate inducted signals. The analog-to-digital converter converts the inducted signals into digital signals. The mixer includes an in-phase multiplier, a quadrature multiplier, an in-phase summer, a quadrature summer and a Pythagorean operator. The in-phase multiplier multiplies each digital signal with a first reference signal to generate in-phase modulated signals. The quadrature multiplier multiplies each digital signal with a second reference signal to generate quadrature modulated signals. The in-phase summer respectively sums up elements of each modulated signal to generate in-phase values. The quadrature summer respectively sums up elements of each quadrature modulated signal to generate quadrature values. The Pythagorean operator performs a Pythagorean operation on each in-phase value and each quadrature value for determining a touch location information corresponding to the sensing pixels.
