UCC28051: multiplier filter

Part Number: UCC28051

Hello

       在查看UCC28051的date sheet资料时,文中说,乘法器输入加的滤波器转折频率建议大于最小开关频率。是不是我翻译的错误?我认为滤波器转折频率应该小于最小开关频率,也就是滤掉所有开关频率。

         1:如果翻译正确,那意思是让滤波器不要滤掉最小开关频率么?

          2:如果翻译不正确,那能否帮我翻译一下,是什么意思?

       When looking at the date sheet of UCC28051, the text says that the corner frequency of the filter added to the multiplier input is recommended to be greater than the minimum switching frequency. Is it my translation error? I think that the filter corner frequency should be less than the minimum switching frequency, that is, to filter out all switching frequencies.
          1: If the translation is correct, does it mean that the filter should not filter out the minimum switching frequency?
           2: If the translation is incorrect, can you translate it for me? What does it mean?

Thankyou
