-  The four analog signals, X+, X-, Y+, Y- comprise the X and Y plate electrodes. To determine the touch coordinates, users must bias the plates and measure the resistive divider formed by the electrically charged resistive plates using an analog-to-digital converter (ADC) count. When operators use the Shanghai Tianma with system boards that have XADC support, they can use the AMS header to digitalize the analog touch panel signals. An on-board analog multiplexer (MUX) switch helps users select the correct panel electrodes for measurement.+The four analog signals, X+, X-, Y+, Y- comprise the X and Y plate electrodes.
