IIR transfer functions Since classical analog filters are IIR filters, there has been a long history of studying the range of possible transfer functions implementing various of the above desired filter responses in continuous time systems.

A closeup of the Indian Nag Missile head, with the Imaging Infrared (IIR) Seeker Germany developed a design for a wire-guided anti tank missile derived from the Ruhrstahl X-4 air to air missile concept in the closing months of World War II.

A digital IIR filter can generally approximate a desired filter response using less computing power than a FIR filter, however this advantage is more often unneeded given the increasing power of digital processors.

An IIR filter can thus be much more efficient in such cases.

Another major development was the AGM-65D, which employed an imaging infrared (IIR) seeker.

By imaging on radiated heat, the IIR is all-weather operable as well as showing improved performance in acquiring and tracking the hot engines, such as in tanks and trucks, that were to be one of its major missions.

Digital filters are typically considered in two categories: infinite impulse response (IIR) and finite impulse response (FIR).

Either IIR or FIR filters may be used, but FIR have the advantage that transients are suppressed if the fractional delay is changed over time.

FIR filters are always stable, while IIR filters may be unstable.

FIR filters can be made to have zero phase, but with IIR filters that is generally impossible.

IIR digital filters are often more difficult to design, due to problems including dynamic range issues, quantization noise and instability.

The general form of an IIR filter is thus: : Plotting the impulse response will reveal how a filter will respond to a sudden, momentary disturbance.

These are often referred to as infinite impulse response (IIR) filters and finite impulse response (FIR) filters, respectively.

These filterbanks may contain either finite impulse response (FIR) or infinite impulse response (IIR) filters.

This filter is an infinite-impulse-response (IIR) single-pole low-pass filter.

Using digital computers, on the other hand, both FIR and IIR filters are straightforward to implement in software.

Using the "convolutional" terminology, a classic convolutional code might be considered a Finite impulse response (FIR) filter, while a recursive convolutional code might be considered an Infinite impulse response (IIR) filter.

With most IIR transfer functions there are related transfer functions having a frequency response with the same magnitude but a different phase; in most cases the so-called minimum phase transfer function is preferred.
