Note: H0 is high pass filter and H1 is low pass filter.
Each frame is low pass filtered (LPF) and sub-sampled prior to predicting low spatial-resolution frame.
The pseudonoise sequence is low pass filtered according to the signal characteristics (the Butterwort filter is used).
The first filter g is high pass in nature and the second h is its mirror version which is low pass in nature.
The low-cut ratio can vary between 0 (indicating that responses are completely attenuated at low frequencies) and 1 (indicating that the tuning function is low pass).
Finally, the frequency output is low-pass filtered and decimated.
The proposed circuit can realize three kinds of filter response that is low-pass, high-pass and band-pass filters from the same configuration.
The output photocurrent is low-pass-filtered (Mini-Circuits, BLP-1.9+) and demodulated by a lock-in amplifier (HF2LI, Zurich Instrument).
Then means the tone with an interrupted interval in the middle (from 225 to 257 ms). is low-pass noise to be inserted into that interrupted interval.
However, while the chromatic spatial frequency tuning is low-pass in humans, it can be low-pass or band-pass in single cortical neurons (Thorell et al. 1984; Lennie et al. 1990; Leventhal et al. 1995; Johnson et al. 2001, 2004, 2008).
where and are low pass signals and is the center frequency of the Fourier transform of and.
