In signal processing, a finite impulse response (FIR) filter is a filter whose impulse response (or response to any finite length input) is of finite duration, because it settles to zero in finite time. This is in contrast to infinite impulse response (IIR) filters, which may have internal feedback and may continue to respond indefinitely (usually decaying).
The impulse response (that is, the output in response to a Kronecker delta input) of an Nth-order discrete-time FIR filter lasts exactly N+1 samples (from first nonzero element through last nonzero element) before it then settles to zero.
For a causaldiscrete-time FIR filter of order N, each value of the output sequence is a weighted sum of the most recent input values:
where:
is the input signal,
is the output signal,
is the filter order; an th-order filter has terms on the right-hand side
is the value of the impulse response at the i'th instant for of an th-order FIR filter. If the filter is a direct form FIR filter then is also a coefficient of the filter .
In signal processing, the impulse response, or impulse response function (IRF), of a dynamic system is its output when presented with a brief input signal, called an impulse. More generally, an impulse response refers to the reaction of any dynamic system in response to some external change. In both cases, the impulse response describes the reaction of the system as a function of time (or possibly as a function of some other independent variable that parameterizes the dynamic behavior of the system).
In all these cases, the dynamic system and its impulse response may be actual physical objects, or may be mathematical systems of equations describing such objects.
Since the impulse function contains all frequencies, the impulse response defines the response of a linear time-invariant system for all frequencies.
Mathematical considerations
Mathematically, how the impulse is described depends on whether the system is modeled in discrete or continuous time. The impulse can be modeled as a Dirac delta function for continuous-time systems, or as the Kronecker delta for discrete-time systems. The Dirac delta represents the limiting case of a pulse made very short in time while maintaining its area or integral (thus giving an infinitely high peak). While this is impossible in any real system, it is a useful idealisation. In Fourier analysis theory, such an impulse comprises equal portions of all possible excitation frequencies, which makes it a convenient test probe.

Introduction to FIR Filters
A brief introduction to how Finite Impulse Response (FIR) filters work for digital signal processing. FIR filters are commonly used in, e.g., digital down-conversion applications to filter an incoming signal before down-sampling it. FIR filters are relatively straight-forward to implement on a variety of digital processing platforms, and are most easily understood as a convolution in time domain, corresponding to a multiplication in frequency domain by the corresponding filter response.

Frequency Response of Finite-Impulse Response Systems
The frequency response of a system is the amplitude and phase change the system introduces as a function of the frequency of a sinusoid input. Systems that have finite-duration impulse responses have frequency response with a particularly simple form.
Lets kick off, what I plan to be, an occasional series on various aspects of digital sound processing with a look at finite Impulse Response (FIR) filters.
These are usually discussed in a heavily mathematical way - involving the square root of minus one. Let's develop a more intuitive, less mathematical, way of understanding FIR filters and calculating the values required to get the frequency response we require.
Let's also have a look at a couple of interesting FIR based applications.

Finite Impulse Response (FIR) and Infinite Impulse Response (IIR) Filters
http://adampanagos.org
This video provides a short introduction to two different classes of digital filters. Infinite impulse Response (IIR) Filters have a filter output that depends on current and past inputs, as well as current and past outputs. As such, these filters are recursive in nature, and a single impulse input will result in a non-zero response that lasts for all time. Thus, the terminology of an “infinite” length impulse response. Finite Impulse Response (FIR) filters have an output that does not depend on any current or past outputs. These filters are not recursive in nature. As such, a single impulse will result in a non-zero filter output only for a finite length of time, and thus the terminology of a “finite” length impulse response.

is the output signal,
is the filter order; an th-order filter has terms on the right-hand side
is the value of the impulse response at the i'th instant for of an th-order FIR filter. If the filter is a direct form FIR filter then is also a coefficient of the filter .
Key features of Dove 850 ... Technical benefits of Dove 850 ... Dove 850’s line side transmitters boast multi-tap Finite Impulse Response (FIR) filters and non-linear correction, facilitating the use of multi-mode or single-mode optics ... ....
Also for power reduction, the PLL is an all-digital two-stage design and, to improve ranging performance without breaking the spectrum regulations, and analogue FIR (finite impulse response) based Tx pre-emphasis pulse shaping approach has been used.
From here, the script can create live graphs, make real-time measurements, and even build up images as they're scanned in microscopy applications.Finite Impulse Response (FIR) Filter BuilderThe FIR ...
