Periodic signal average value determination method, in which the signal is sampled over a signal period and the average of the difference of the sample values and the moving average is determined and added to the moving average

摘要

Method for forming the average value of a periodic signal has the following steps: sampling of the periodic signal within a signal period; determination of the difference between each of the sample values and the average valve of the preceding periods; formation of the average value of the differences and; addition of the average valve of the difference values to the moving average value determined for preceding periods. An Independent claim is made for a device for forming the average value of a periodic signal that comprises a memory unit, a difference formation unit and an average value formation unit.
