FIR vs IIR filtering Infinite impulse response (IIR) filters. IIR filters are the most efficient type of filter to implement in DSP (digital signal processing). They are usually provided as biquad filters. For example, in the parametric EQ block of a miniDSP plugin, each peak/notch or shelving filter is a single biquad.

ISAPI Filter Overview The ability to examine and modify both incoming and outgoing streams of data makes ISAPI filters powerful and flexible. Filters are registered at either the site level or the global level (that is, global filters apply to all sites on the IIS server), and are initialized when the worker process is started.

Magnetic ink character recognition Magnetic Ink Character Recognition Code (MICR Code) is a character-recognition technology used mainly by the banking industry to ease the processing and clearance of cheques and other documents.ICR characters are printed on a document in either of the MICR fonts. The ink used in the printing is a magnetic ink or toner, usually containing iron oxide. The MICR text is passed before a MICR reader.

Near-infrared spectroscopy Near-infrared spectroscopy (NIRS) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from about 700 nm to 2500 nm).nstrumentation for near-IR (NIR) spectroscopy is similar to instruments for the UV-visible and mid-IR ranges. There is a source, a detector, and a dispersive element (such as a prism, or, more commonly, a diffraction grating) to allow the intensity at different wavelengths to be recorded.

Difference Between IIR and FIR Filters Where the system response is infinite, we use IIR filters, and where the system response is zero, we use FIR filters. FIR filters are also preferred over IIR filters because they have a linear phase response and are non recursive, whereas IIR filters are recursive, and feedback is also involved.
