More Information
Summary:Standard deviation determining apparatus includes an integrator for integrating changes exhibited by a random variable, a circuit for selecting integrator output signals and a further circuit for averaging signals selected by the selecting circuit. The apparatus provides for periodic resetting of the integrator, for selecting integrator output signals occurring during predetermined time periods and for maintaining the integrator output constant in amplitude during the selecting of signals therefrom.
