Abstract:
A noise spectrum estimator for a touch panel includes an adaptive impulse response generation unit configured to generate impulse response information by performing an adaptive training operation on noise data, the noise data being generated by sampling a plurality of noise signals received from the touch panel, and an estimation unit configured to generate noise frequency spectrum estimation information associated with the noise data by performing a fast Fourier transform (FFT) on the impulse response information.
