Kusefa
NI-9218 imagwiritsa ntchito kuphatikizika kwa analogi ndi kusefa kwa digito kuti ipereke chifaniziro cholondola cha ma sigino apakati pomwe ikukana ma siginolo akunja. Zosefera zimasankha pakati pa ma siginecha potengera kuchuluka kwa ma frequency, kapena bandwidth, chizindikiro. Ma bandwidth atatu ofunika kuwaganizira ndi passband, stopband, ndi alias-free bandwidth.
NI-9218 imayimira zizindikiro mkati mwa passband, monga momwe zimakhalira makamaka ndi passband ripple ndi gawo losagwirizana. Zizindikiro zonse zomwe zimawoneka mu bandwidth yopanda alias mwina ndi zizindikiro zosasinthika kapena zizindikiro zomwe zasefedwa ndi kuchuluka kwa kukana kwa stopband.

Chiphaso

Zizindikiro zomwe zili mkati mwa passband zimakhala ndi phindu lodalira pafupipafupi kapena kuchepetsedwa. Kuchepa kwapang'onopang'ono pakupindula pokhudzana ndi pafupipafupi kumatchedwa passband flatness. Zosefera za digito za NI-9218 zimasintha ma frequency angapo a passband kuti agwirizane ndi kuchuluka kwa data. Chifukwa chake, kuchuluka kwa phindu kapena kuchepetsedwa pafupipafupi kumatengera kuchuluka kwa data.

Choyimitsa
The filter significantly attenuates all signals above the stopband frequency. The primary goal of the filter is to prevent aliasing. Therefore, the stopband frequency scales precisely with the data rate. The stopband rejection is the minimum amount of attenuation applied by the filter to all signals with frequencies within the stopband.

Bandwidth Alias-Free
Chizindikiro chilichonse chomwe chimawoneka mu bandwidth yopanda mawu ya NI-9218 sichinthu chodziwika bwino cha ma siginali pafupipafupi. Bandiwifi yaulere ya alias imatanthauzidwa ndi kuthekera kwa fyuluta kukana ma frequency pamwamba pa ma frequency a stopband, ndipo ndi ofanana ndi kuchuluka kwa data kuchotsera ma frequency a stopband.
