Discrete Low-Pass Filter












0















After passing my data through a discrete derivative it gives me very noisy peaked data but I would like to change this without compromising system stability.



How is it possible to implement a discrete low pass filter in simulink without the use of a subsystem. I havent been able to find a block to do this.



However if this isn't possible how would i model a subsystem to give the desired effect.

          The Discrete Library has both a Discrete Transfer Function and Discrete Filter block, either of which can be used for a discrete filter - nothing to do with subsystems.



          Note that you should almost never model using derivatives - discrete or continuous - because it will introduce noise. And that there will always be a trade off between performance and stability, so asking how to do something without compromising system stability isn't really a sensible question.

            Note that you should almost never model using derivatives - discrete or continuous - because it will introduce noise. And that there will always be a trade off between performance and stability, so asking how to do something without compromising system stability isn't really a sensible question.
