DIGITIZE WAVEFORMS WITH ANTI-ALIASING FILTERS APPLICATIONS > ANALOG LOW PASS FILTERS >
The
8-Pole i500
analog low pass filter daughterboard, which installs onto an
i423 card, is ideal for
anti-aliasing.
For a summary of anti-aliasing and why you might need an AFS filter, click
here.
The i500 provides extremely low ±0.01 dB maximum passband
ripple for Fin/Fc ≤ 0.5.
If one uses further
oversampling, digital filtering and
desampling; then passband ripple
is ±0.002 dB for Fin/Fc ≤
0.8 due to the accuracy of a 30-pole digital filter.
The end user installs between 1 and 6 filter daughterboards onto each
i423 card, one per channel.
