What are the two types of digital filters?

There are two fundamental types of digital filters: finite impulse response (FIR) and infinite impulse response (IIR).

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.

What are the differences between FIR filter and IIR filter?

If the impulse response of the filter falls to zero after a finite period of time, it is an FIR (Finite Impulse Response) filter. However, if the impulse response exists indefinitely, it is an IIR (Infinite Impulse Response) filter.

What do you mean by a filter compare digital filters with analog filters?

Digital and analog filters both take out unwanted noise or signal components, but filters work differently in the analog and digital domains. Analog filters will remove everything above or below a chosen cutoff frequency, whereas digital filters can be more precisely programmed.
