What is FIR?

FIR (Finite Impulse Response) refers to a type of digital filter whose impulse response settles to zero in finite time, because it has no feedback. This is in contrast to IIR (Infinite Impulse Response) filters, which use feedback and may continue to respond indefinitely. FIR filters are commonly used in digital signal processing for tasks such as audio processing, image processing, and data filtering due to their inherent stability and ability to be designed with linear phase response.
