<p>A circuit with hysteresis for converting an analog signal into a logic signal. In response to the state of the feedback signal from a microcomputer, a signal proportional to the analog signal is either intensified for providing a lower threshold value or diminished for providing an upper threshold value. By recognising the intensified and diminished signals with respect to a predetermined value, the analog signal is converted to a two-state signal.</p> |
