An exemplary method of identifying a touch event on a touch panel is provided. The touch panel includes a plurality of sensing blocks. The sensing blocks have a plurality of corresponding sensing values generated in response to the touch event. The exemplary method includes the following steps: selecting a processing region on the touch panel, wherein the processing region comprises at least a portion of sensing blocks each having a sensing value greater than a threshold; deriving a first value and a second value from sensing values of sensing blocks included in the processing region; calculating a ratio of the first value to the second value; and identifying the touch event according to at least the ratio.

A monitoring method with a function of correlation-based system identification applicable for a digitally controlled DC-DC converter system is revealed. The monitoring method includes a plurality of steps. After the system is operated in a steady state, input a pseudo random binary sequence signal into the system via a pseudo random binary sequence generator and store the pseudo random binary sequence signal and an output signal of a path to be monitored in a memory unit. Then perform a correlation analysis of data stored in the memory unit by a correlation analysis module and output an impulse response. Next obtain a frequency response of the impulse response by a discrete-time Fourier transform module. Finally, smooth the frequency response by an adaptive sliding window smoothing module so that a monitoring curve of the frequency response becomes smooth.
