查询词典 modulation

By spatially and temporally analyzing of the NSD which describes the normative difference of predicted SAD and minimum SAD after motion estimation, as well as the assumption that residual signal is Laplacian distribution, a modulation factor is given to realize early termination, thus a tradeoff between search speed and reconstructed video quality can be achieved.

The results showed that the echolocation calls of the leaf-nosed bats were constant frequency-frequency modulation signals with 2-3 harmonics and the second one among these three harmonics was its dominant frequency. The constant frequency components of three harmonics (Mean±SD, n=18 ) were 33.3±0.2 kHz, 66.5±0.3 kHz, and 99.4±0.5 kHz, respectively. In examined FTCs of 72 IC neurons, their Q 10 -dB values ranged from 0.5 to 95.4 (9.2±14.6) and the neurons whose best frequency around the dominant frequency had sharp frequency tuning.
