摘要：
A method of generating a MPWM signal for a portable device such as a cellular telephone. For a first duty cycle that includes a MPWM frequency having N magnitude levels, the method generates a first waveform comprising a first and a second On pulse during a first MPWM frequency period. The first and second On pulses are separated by an Off period.
