Abstract
A method is described for determining and indicating the time mean of a measured quantity as a function of its period of operation. A signal is generated responsive to the exceeding of a predetermined pair of values or coordinates of mean and period of operation of the quantity being measured. The measured quantity is integrated, and an extinguishing quantity is superimposed on the measured quantity. The value of the extinguishing quantity as a function of the instantaneous value of the quantity being measured is chosen so that a uniform storage state of the integrator corresponds with the pairs of values of mean of the quantity being measured and its period of operation.
Claims2
A method for measuring the time mean of a quantity being measured as a function of its period of operation, comprising the steps of:
- applying the quantity being measured to an integrator,
- producing a constant extinguishing quantity which is a function of at least two predetermined pairs of values for said time mean and the integration period of the quantity being measured and which is of a value such that the storage capacity of said integrator is uniform for said predetermined pairs of values for said time mean and the integration period of the quantity being measured,
- superimposing said extinguishing quantity on said quantity being measured and
- generating a signal from the values stored in said integrator responsive to the exceeding of said value pairs.
