Abstract
Official abstract text for this publication.
A modulation method is provided. The modulation method includes the steps of receiving multiple sinusoidal signals, obtaining the maximum value of the sinusoidal signals, obtaining the median value of the sinusoidal signals, and obtaining the minimum value of the sinusoidal signals within a period to generate a difference between the maximum value and the minimum value, generating a difference according to an upper limit and a lower limit of a predetermined comparison value, and comparing the two differences to generate an optimized modulation signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A modulation method applied to a control device, comprising: receiving a plurality of sinusoidal signals; within a period, obtaining a maximum value, a median value and a minimum value of the sinusoidal signals to generate a first difference between the maximum value and the minimum value; generating a second difference according to an upper limit and a lower limit of a predetermined comparison value; and comparing the first difference with the second…
