Iragazkia
The NI-9218 uses a combination of analogue and digital filtering to provide an accurate representation of in-band signals while rejecting out-of-band signals. The filters discriminate between signals based on the frequency range, or bandwidth, of the signal. The three important bandwidths to consider are the passband, the stopband, and the alias-free bandwidth.
NI-9218ak banda-pasabideko seinaleak adierazten ditu, batez ere banda-pasabideko uhinaren eta fase-ez-linealtasunaren bidez kuantifikatuta. Aliasik gabeko banda-zabaleran agertzen diren seinale guztiak aliasik gabeko seinaleak edo gelditze-bandaren bazterketaren gutxienez kantitatearen arabera iragazi diren seinaleak dira.

Pasabanda

Pasa-bandaren barruko seinalek maiztasunaren araberako irabazia edo deuseztatzea dute. Maiztasunarekiko irabazian dagoen aldaketa txikiari pasa-bandaren lautasuna deritzo. NI-9218aren iragazki digitalek pasa-bandaren maiztasun-tartea doitzen dute datu-abiadurarekin bat etortzeko. Beraz, maiztasun jakin batean irabaziaren edo deuseztatzearen kopurua datu-abiaduraren araberakoa da.

Gelditzeko banda
Iragazkiak nabarmen ahultzen ditu stopband maiztasunaren gainetik dauden seinale guztiak. Iragazkiaren helburu nagusia aliasing-a saihestea da. Beraz, stopband maiztasuna zehaztasunez eskalatzen da datu-abiadurarekin. Stopband baztertzea iragazkiak stopband barruan maiztasunak dituzten seinale guztiei aplikatzen dien ahultze-kopuru minimoa da.

Aliasik gabeko banda-zabalera
Any signal that appears in the alias-free bandwidth of the NI-9218 is not an aliased artefact of signals at a higher frequency. The alias-free bandwidth is defined by the ability of the filter to reject frequencies above the stopband frequency, and it is equal to the data rate minus the stopband frequency.
