Hi eveyone, I would like to know if possible to replace the unit_delay blok (it is presented in figure below) by another blok which exists in the simulink tool. or another method than this. if yes which one ? Thanks

I did not understand its relationship with the unit_delay blok

[Walter Roberson]

The blog talks about the different methods that can be used to delay signals: memory blocks, unit delay, and transfer functions. You do not want to use a unit delay block, so that leaves you with memory blocks or transfer functions.

What's wrong with using the unit delay block? Hard to know what might be a potential replacement without knowing the problem you're trying to solve.
