3rd-order high-pass filter in which the native response of tweeter provides the 2nd-order part of the transfer function and the series capacitor provides the 1st-order part. (7.142)p˜(r)=e˜gBISDρ0(Rg+RE)MMS·e−jkr4πrG(s) where the 3rd-order frequency-response function G(s)...
1. System for methodically adjusting the acoustical volume Vand the passive 2nd order L, C - highpass filter of an electrodynamic driver in a closed box to the total quality factor Q, to the mechanical quality factor Qand to the drivers resonance frequency fmeasured without enclosure in each ...
After reconstructing all the 240 (0.5 × 60 × 8 = 240) time sequential images, a second-order Butterworth bandpass filter (0.008–0.09 Hz) was first applied to all temporal sequences, followed by a global signal regression based on the time sequences of all pixels ...
Allpass digital filters are major building blocks in many digital filter architectures. In this paper an optimal pipelined architecture for a 2nd order allpass section based on 3-port adaptor is proposed. Optimal pipelining improves the filter's overall performance in term of power-delay-area by ...
The recorded signals were filtered and digitized through the Intan USB interface board software (20 kS⋅s−1 per channel, 300 Hz high pass filter, 6 kHz low pass filter). For optical stimulation to the 3D neural model, we used a custom-designed LED drive that adjected the ...

(ii) an active, 1st order high-pass filter that enhances the dc offset rejection capabilities of the AFE; and (iii) a passive, 2nd order low-pass filter that defines the passband of the AFE and also serves as an anti-alias filter for the analog-to-digital converter (ADC) stage, which...
(z)) represent the even parts (odd part) of the low-pass and high-pass filters, respectively.si(z) andti(z) are denoted as predict lifting and update lifting polynomials.Kand 1/Kare scale normalization factors. Factorization of classical wavelet filter into lifting steps reduces the ...
LFPs were obtained by downsampling the data to 1.25 kHz and filtering using a 1,000-Hz low-pass filter. Full fCWT and CWT, 3.0%CWT (EEG section), STFT and DWT time–frequency estimations were performed on 9 s of raw single-trial LFP data containing four stimuli. We compared CWT...
To minimize the interference fringes on the BFP images, we used a noncoherent light (tungsten bromine lamp combined with a serials of band-pass filters) as the illumination source. The center wavelengths of the band pass filter ranges from 600 to 790 nm (20 filters in total), with a ...
