Ukuhlunga
I-NI-9218 isebenzisa inhlanganisela yokuhlunga kwe-analogue nedijithali ukuze inikeze ukumelwa okunembile kwamasignali angaphakathi kwebhendi kuyilapho yenqaba amasignali angaphandle kwebhendi. Izihlungi zibandlulula phakathi kwamasignali ngokusekelwe kububanzi befrikhwensi, noma umkhawulokudonsa, wesiginali. Imingcele emithathu ebalulekile okufanele icatshangelwe yi-passband, i-stopband, kanye ne-alias-free bandwidth.
I-NI-9218 imele amasiginali ngaphakathi kwebhendi yokudlula, njengoba ibalwa ngokuyinhloko ngokuzwakala kwe-passband ripple kanye ne-phase nonlinearity. Wonke amasiginali avela kumkhawulokudonsa ongena-alias amasiginali angahlukanisiwe noma amasiginali ahlungwe okungenani inani lokwaliwa kwe-stopband.

I-passband

Amasignali angaphakathi kwebhendi yokudlula anokuzuzwa noma ukuncipha okuncike kufrikhwensi. Inani elincane lokwehluka kwenzuzo ngokuphathelene nemvamisa kubizwa ngokuthi i-passband flatness. Izihlungi zedijithali ze-NI-9218 zilungisa ibanga lemvamisa yebhendi yokudlula ukuze ifane nenani ledatha. Ngakho-ke, inani lenzuzo noma ukuncipha emvamisa ethile lincike esilinganisweni sedatha.

Ibhande lokumisa
Isihlungi sinciphisa ngokuphawulekayo wonke amasignali ngaphezu kwefrikhwensi ye-stopband. Umgomo oyinhloko wesihlungi ukuvimbela ukubizwa ngamagama. Ngakho-ke, imvamisa ye-stopband sikala ngokunembile nenani ledatha. Ukwenqatshwa kwe-stopband inani elincane lokuncishiswa elisetshenziswa isihlungi kuwo wonke amasignali anefrikhwensi ngaphakathi kwebhande lokumisa.

I-Alias-Free Bandwidth
Noma iyiphi isignali evela kumkhawulokudonsa ongena-alias we-NI-9218 akuyona i-artefact engaziwa yamasiginali emazingeni aphezulu. I-alias-free bandwidth ichazwa ikhono lesihlungi ukwenqaba amafrikhwensi angaphezu kwefrikhwensi ye-stopband, futhi lilingana nezinga ledatha kukhishwe i-stopband frequency.
