Web6 mei 2016 · An integrator is one kind of low pass filter. It's a "filter", because it is linear and time-invariant (LTI), and it is "low pass" because its low-frequency response is bigger than its high-frequency response. But perfect integrators are not typically used by themselves (in DSP) for any tasks that you would call "low-pass filtering".
