© National Instruments Corp. 13 NI 9229/9239 Understanding NI 9229/9239 Filtering The NI 9229/9239 u ses a combination of analog and digital filtering to provide an acc u rate representation of in-band signals while rejecting o u t-of-band signals. The filters discriminate between signals based on t...

© National Instruments Corp. 15 NI 9229/9239 Stopband The filter significantly atten u ates all signals above the stopband freq u ency. The primary goal of the filter is to prevent aliasing. Therefore, the stopband freq u ency scales precisely with the data rate. The stopband rejection is the minim ...
