Signal processing system, touch panel controller, and touch panel system and electronic device using the same

摘要

The signal processing system (10) estimates the value of the linear element (CX) by performing signal processing based on addition and subtraction based on the noise frequency, noise amount, and input / output transfer characteristics mixed in the time series signal. A switching circuit (6) for switching the subsystems (5a, 5b) is provided so as to reduce mixed noise.
