PHASE SHIFT REDUCTION IN TOUCH SIGNALS
摘要:
Phase shift reduction in touch signals is disclosed. Touch signals with phase shifts can be demodulated with I- and Q-demodulation waveforms to generate the I and Q components of the signals. The I and Q components can then be combined so as to provide magnitude information not affected by the phase of the touch signals. The touch signals can be reconstructed with the combined I and Q components, thereby providing reconstructed touch signals with little or no phase shift.
