How can I correct the settling time when implementing a pre-filter (reference filtering)?

1. What is a prefilter in control systems?
2. What are the 4 categories of digital filtering?
3. Which of the application's filters used for eliminating AC components from a signal?

What is a prefilter in control systems?

The prefilter traps large particles such as dust, oil, and carbon (from the compressor), and pipescale and rust (from the pipework) and thus protects the sterilizing filter and increases its lifetime.

What are the 4 categories of digital filtering?

There are two categories of digital filter: the recursive filter and the nonrecursive filter. These are often referred to as infinite impulse response (IIR) filters and finite impulse response (FIR) filters, respectively.

Which of the application's filters used for eliminating AC components from a signal?

In the field of signal processing, a filter is a device that suppresses unwanted components or features from a signal. The most commonly used filters are low-pass, high-pass, band-pass and band-stop.
