请帮我看看gardner93年文献里的几句话，谢谢！

If Ts were commensurate with Ti,but not equal,then Uk were cyclicly repeat
a finite set of values,when the timing loop is in equilibrium.
主要是If这一句，我不知道 If Ts were commensurate with Ti该怎么理解才好，理解成：如果Ts和Ti相称（或成比例）。
还有类似的：
a commensurate ratio 该怎么翻译和理解？
In general,Ti/Ts is irrational;the sampling and symbol rates are incommensurate.这句话该怎么翻译和理解？
Since a modem is required to perform filtering of signals there is no reason why some of the filtering cannot be included in the interpolator.
这句话该怎么理解和翻译？
我英语很弱，请大家帮我翻译一下，拜谢先！

1. commensurate 可度量的，成比例的，与下文的irrational对应
   如Ts/Ti=M/N, 则插值时u=mod(n*Ts/Ti,1)按一定规律变化
2. commensurate ratio = 上例的M/N
3. 通常Ts/Ti是无理数，因此Ts/Ti导致插值时呈现无规律性
4. interpolation也是一种滤波器，因此modem中某些滤波功能
   可以和插值滤波一起完成。
