+Description:
+ Reading returns a list with the possible filter modes.
+
+ * "sinc4" - Sinc 4. Excellent noise performance. Long
+ 1st conversion time. No natural 50/60Hz rejection.
+
+ * "sinc4+sinc1" - Sinc4 + averaging by 8. Low 1st conversion
+ time.
+
+ * "sinc3" - Sinc3. Moderate 1st conversion time.
+ Good noise performance.
+
+ * "sinc3+rej60" - Sinc3 + 60Hz rejection. At a sampling
+ frequency of 50Hz, achieves simultaneous 50Hz and 60Hz
+ rejection.
+
+ * "sinc3+sinc1" - Sinc3 + averaging by 8. Low 1st conversion
+ time. Best used with a sampling frequency of at least
+ 216.19Hz.
+
+ * "sinc3+pf1" - Sinc3 + Post Filter 1. 53dB rejection @
+ 50Hz, 58dB rejection @ 60Hz.
+
+ * "sinc3+pf2" - Sinc3 + Post Filter 2. 70dB rejection @
+ 50Hz, 70dB rejection @ 60Hz.
+
+ * "sinc3+pf3" - Sinc3 + Post Filter 3. 99dB rejection @
+ 50Hz, 103dB rejection @ 60Hz.
+
+ * "sinc3+pf4" - Sinc3 + Post Filter 4. 103dB rejection @
+ 50Hz, 109dB rejection @ 60Hz.

+Description:
+ Set the filter mode of the differential channel. When the filter
+ mode changes, the in_voltageY-voltageZ_sampling_frequency and
+ in_voltageY-voltageZ_sampling_frequency_available attributes
+ might also change to accommodate the new filter mode.
+ If the current sampling frequency is out of range for the new
+ filter mode, the sampling frequency will be changed to the
+ closest valid one.
