or signals that have been filtered by at least the amount of the

stopband rejection.

Passband

The signals within the passband have frequency-dependent gain or

attenuation. The small amount of variation in gain with respect to

frequency is called the passband flatness. The digital filters of the

NI 9237 adjust the frequency range of the passband to match the

data rate. Therefore, the amount of gain or attenuation at a given

frequency depends on the data rate. Figure 4 shows typical

passband flatness for the NI 9237.
