  • A filter whose output is a weighed sum of the current and past inputs. It is one of the two primary types of filters utilized in digital signal processing, the other being Infinite-impulse response filters. Finite-Impulse Response Filters tend to be more linear, but less efficient than Infinite-Impulse Response filters. Its abbreviation is FIR filter. Also called transversal filter.
