Sentence examples for filtered below from inspiring English sources

The group-concatenated amplitude envelopes were low pass filtered below 0.5 Hz to remove any higher frequency dynamics and an 8 state HMM was inferred from these filtered envelopes.

Correlation maps, mean life times, and fractional occupancy time window dependency for 8 state HMMs inferred from (A ) the original group-concatenated envelopes, (B ) these envelopes low pass filtered below 0.5 Hz and (C ) these low pass filtered envelopes with uncorrelated Gaussian noise added.

EEG data was high-pass filtered above 0.1 Hz and then low-pass filtered below 30 Hz (5th order two-pass Butterworth filters).

EEG was were then low-pass filtered below 20 Hz (5th order two-pass Butterworth filter), and a notch-filter at 50 Hz was also applied to reduce line noise.

(1) To assess the amplitude of TMS-evoked slow waves, single trials were low-pass filtered below 4 Hz (third-order Chebyshev filtering as in ref. 10), re-referenced to the mathematically linked mastoids, averaged and eventually rectified.
