You can design both finite impulse response (FIR) and infinite impulse response (IIR) digital filters using the LabVIEW Digital Filter Design Toolkit: FIR—The output signal of the filter, after you set the input signal from nonzero to zero, can be nonzero for only a fini...
FIR filters are more powerful than IIR filters, but also require more processing power and more work to set up the filters. They are also less easy to change "on the fly" as you can by tweaking (say) the frequency setting of a parametric (IIR) filter. However, their greater power mean...

Analog filters beyond 10 poles are very difficult to realize and tend to be noisy. 2) The floating-point DSP and IIR implementations Like its name, floating point DSP’s can perform floating-point math, which greatly decreases truncation noise problems and allows more complicated filter structures...
摘要: Presents a study that introduced a novel hybrid adaptive far-infrared radiation (FIR) and isobutylene-isoprene rubber (IIR) filter configuration to reduce the main obstacles limiting the use of adaptive IIR filters. Discussion on adaptive algorithms; FIR-IIR hybrid scheme; Illustrative example....

Filters can be both IIR and FIR. IIR filters are implemented as biquads, while FIR use convolution via FFT/IFFT. A filter can be applied to any number of channels. All processing is done in chunks of a fixed number of samples. A small number of samples gives a small in-out latency ...
