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. Source: Internet
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. Source: Internet
Another major development was the AGM-65D, which employed an imaging infrared (IIR) seeker. Source: Internet
An IIR filter can thus be much more efficient in such cases. Source: Internet
Digital filters are typically considered in two categories: infinite impulse response (IIR) and finite impulse response (FIR). Source: Internet
