What are types of digital filter?

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

What are digital filters used for?

Digital filters are used for two general purposes: (1) separation of signals that have been combined, and (2) restoration of signals that have been distorted in some way. Analog (electronic) filters can be used for these same tasks; however, digital filters can achieve far superior results.

What are the different types of filter?

The four primary types of filters include the low-pass filter, the high-pass filter, the band-pass filter, and the notch filter (or the band-reject or band-stop filter).

What are 3 advantages of digital filters?

Digital filters require only the arithmetic operations of addition, subtraction, and multiplication. Digital filters do not drift with temperature or humidity or require precision components. Digital filters have a superior performance-to-cost ratio. Digital filters do not suffer from manufacturing variations or aging.
