METHOD AND APPARATUS FOR FORMING SIGNAL CORRESPONDING TO FUNCTION

Document Type and Number:

Japanese Patent JPH01188984

Kind Code:

A

Abstract:

PURPOSE: To obtain the value or a function (z) in a simple method without the sampling error by calculating an average value z' of a function x+a.dy/dt averaged for one sampling interval without calculating the accurate instantaneous value of the function. CONSTITUTION: In the method which generates a signal corresponding to a function x+b.dy/dt derived from two signals (x) and (y) by a microcomputer, a first digital instantaneous value of the signal (y) is sampled at the start of the sampling interval, and a signal corresponding to an integrated instantaneous value of the signal (x) is generated in the duration of the sampling interval, and a second digital instantaneous value of the signal (y) is sampled at the end of the sampling interval, and a signal derived from the difference between the signal corresponding to the integrated instantaneous value of the signal (x) and the sampled instantaneous value of the signal (y) is generated in the duration of the sampling interval by the microcomputer.
