ABSTRACT:
A sphygmomanometer includes a blood pressure detector, a compensation circuit for providing polygonal line approximation functions suitable for piezo-electric characteristics of the blood pressure detector according to compensation data externally applied thereto, and a pressure determination circuit for determining pressure values using the polygonal line approximation functions from the values measured by the blood pressure detector for a predetermined time period.
