As a result, the demodulation bandwidth of "3000" is selected from the table. This
shows that a minimum measurement time of 1.31 seconds is required to capture
3125 of sample rate.

3. Select the appropriate audio lowpass filter from

4. Depending on the sample rate and modulating frequency range, "DBW/1" is

selected as the audio lowpass filter.

5. If a faster measurement time is desired, e.g. 6 ms, the audio lowpass, "DBW/10"

should be selected to fulfill the requirement on the modulating frequency.
