Abstract
A method for reducing the transition rate of a pulse width modulated signal representing an original signal having a predetermined frequency range of interest and producing an output signal, the method including the steps of: combining pulses from a predetermined number of consecutive frames into a combined pulse; and positioning the combined pulse within the predetermined number of consecutive frames, such that the output signal has substantially the same Fourier Transform phase as the pulse width modulated signal, for at least the predetermined frequency range of interest of the original signal.
