Method and device for processing pwm data

A device for processing PWM data, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein, the processor is configured to perform:
• dividing pulse widths in the PWM data into at least one pulse width group;
• determining a convergence pulse width for each of the at least one pulse width group, wherein each of the at least one pulse width group converges around a same pulse width, respectively;
• replacing each of the at least one pulse width group with the corresponding convergence pulse width;
• and
• representing the PWM data by using the convergence pulse widths.

A non-transitory computer readable storage medium, when instructions in the storage medium are executed by a processor of a device, the device is caused to execute the following steps of:

• dividing pulse widths in the PWM data into at least one pulse width group;
• determining a convergence pulse width for each of the at least one pulse width group, wherein each of the at least one pulse width group converges around a same pulse width, respectively;
• replacing each of the at least one pulse width group with the corresponding convergence pulse width;
• and
• representing the PWM data by using the convergence pulse widths.
