    摘要: The DC sensor signal S, on which a low frequency waviness component S1 and a high frequency noise component S2, is obtained by amplitude detecting for a sinusoidal output signal from a touch signal probe. For generating a touch trigger signal TG at an sbrupt DC level transition of the DC sensor signal S, the signal S is input to a LPF 21 to output a signal (S0+S1), where S0 is a DC offset component, and S1 is a low frequency waviness component. The amplitude transforming circuit 22 multiplies the signal (S0+S1) by a coefficient k to generate a reference signal k(S0+S1). The comparator 23 compares the DC sensor signal S with the reference signal to output the touch trigger signal TG at the abrupt DC transition point of the DC sensor signal S.
