Abstract: A modulation method is provided. The modulation method includes steps of: receiving multiple sinusoidal signals; obtaining a maximum value, a median value and a minimum value of the sinusoidal signals within a period 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 difference to generate an optimized modulation signal.
