Hidlo
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.
Mae'r NI-9218 yn cynrychioli signalau o fewn y band pasio, fel y'u meintioli'n bennaf gan ripple band pasio ac anlinoledd cyfnod. Mae pob signal sy'n ymddangos yn y lled band di-alias naill ai'n signalau heb alias neu'n signalau sydd wedi'u hidlo gan o leiaf swm y gwrthodiad band stopio.
band pas
Mae gan y signalau o fewn y band pasio enillion neu wanhad sy'n ddibynnol ar amledd. Gelwir y swm bach o amrywiad mewn enillion mewn perthynas ag amledd yn wastadrwydd y band pasio. Mae hidlwyr digidol yr NI-9218 yn addasu ystod amledd y band pasio i gyd-fynd â'r gyfradd ddata. Felly, mae faint o enillion neu wanhad ar amledd penodol yn dibynnu ar y gyfradd ddata.
Band stop
Mae'r hidlydd yn gwanhau pob signal uwchlaw amledd y band stop yn sylweddol. Prif nod yr hidlydd yw atal aliasing. Felly, mae amledd y band stop yn graddio'n union gyda'r gyfradd ddata. Y gwrthodiad band stop yw'r lleiafswm o wanhau a gymhwysir gan yr hidlydd i bob signal gydag amleddau o fewn y band stop.
Lled Band Di-alias
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.
