  • Sampling type measuring device
    Patent number: 5243276
    Abstract: A sampling type measuring device wherein an analog signal is measured by sampling the analog signal, converting each value obtained by sampling into digital form, and then processing the digital values. Exponential averaging calculation is performed directly on the digital values. Thus, no provision or time is needed to regulate the sampling period, thereby shortening the time required to perform measurement.
    Type: Grant
    Filed: July 20, 1992
    Date of Patent: September 7, 1993
    Assignee: Yokogawa Electric Corporation
    Inventors: Yukio Kashiwabara, Yukiyoshi Hiraishi, Eiichi Goto
