Title: Binarization circuit having noise eliminating function and phase difference detection circuit for vibrator utilizing the binarization circuit
Inventor: HASEGAWA KAZUO
IPC: G01C19/56
Filed: 2000-07-10
Abstract: PROBLEM TO BE SOLVED: To solve the problem that conventionally binarization circuit that cannot obtain a binary signal with high accuracy, because a swinging (noise) takes place at switching of binary signals in the case of applying binarization processing to an input signal with a noise component superimposed thereon. SOLUTION: When an input signal S1' crosses a threshold Vt of a comparator from a higher voltage into a lower voltage, the threshold Vt is temporarily increased up to an upper limit VH, and when the input signal S1' crosses the threshold value Vt of the comparator from a lower voltage into a higher voltage, the threshold Vt is temporarily decreased to a lower limit VL. Since this means that a peak level of a noise component superimposed on the input signal S1' is kept within a range between the upper limit VH and the lower limit VL, a binary signal with high accuracy can be produced, without a swinging (noise) at switching of the input signal.
