Have an issue with MATLAB function: comm.LinearEqualizer.

The MATLAB function comm.LinearEqualizer has an input called: InputDelay.

I read the documentation regarding this input in the comm.LinearEqualizer's link:

https://www.mathworks.com/help/comm/ref/comm.linearequalizer-system-object.html

, but still have an issue.

I do not understand how does the function comm.LinearEqualizer handles this input, is MATLAB shifts the input stream by InputDelay (do not suggest this) or what ?

I need to know as I want to make a code for comm.LinearEqualizer. I have already coded it, and exactly similar results are obtained from my code and MATLAB's comm.LinearEqualizer, but when the input feature: InputDelay does not equal zero, my output deviates from MATLAB output, so I want to know how does MATLAB handle InputDelay value inside its code.

Hint: I have opened the MATLAB function ( comm.LinearEqualizer) itself and can not catch how does MATLAB handle InputDelay parameter.

Why do you want to create your own version of comm.LinearEqualizer instead of using the implementation provided in Communications Toolbox?

Because I want to learn.

Please tell me, is it secret info ?
