Abstract: A touch system is provided. The touch system includes a touch tool and a touch panel. The touch tool provides a downlink signal. The touch panel obtains a first sensing area sensed with the touch tool, and obtains a second sensing area other than the first sensing area according to the downlink signal. The touch panel provides a first uplink signal to the first sensing area, and provides a second uplink signal to the second sensing area. The first uplink signal is different from the second uplink signal. The touch tool generates a calculated uplink signal according to the first uplink signal and the second uplink signal, and provides the downlink signal according to the calculated uplink signal.

Abstract: A determining method and apparatus thereof for a transition point of a sequence which can be applied to a decoder. The determining method determines the transition point of the sequence having N numbers, wherein the sequence is composed of a first value and a second value and N is a positive integer. The determining method includes determining the position the first value appearing consecutively in the sequence to determine a first interval; determining the position the second value appearing consecutively in the sequence to determine a second interval; and determining the longer interval between the first interval and the second interval, when the first interval is longer, determining an adjacency of the first interval and the second value as the transition point according to the first interval, and when the second interval is longer, determining an adjacency of the second interval and the first value as the transition point.

Abstract: A phase digitizing apparatus for generating a corresponding digital value in response to a phase of an input signal is provided. The phase digitizing apparatus includes a coarse phase generator, for generating a coarse phase code according to the phase of the input signal and a first time unit; a fine phase code generator, for generating a fine phase code according to the phase of the input signal and a second time unit; and a calculating unit, for generating the digital value according to the coarse phase code and the fine phase code; wherein the first time unit is greater than the second time unit.
