HRPWM模块产生的PWM波位数怎么计算的?

在HRPWM数据手册中只给出常规PWM的输出精度计算公式,并未给出HRPWM模块产生的PWM精度计算公式,所以我很不明白HRPWM模块产生的PWM波位数怎么计算的?求高人解答!

  • Han,

    Here’s the formula that can be used to calculate HRPWM resolution in bits:

     

    log{(Tpwm)/150ps}/log 2

     

    where Tpwm = PWM switching period = 1/ (PWM switching frequency)
