order or two high-pass network. Then, by simply using an additional RC network, the first-order filter stage can be converted to a second-order type, the same as the 2nd-order low-pass filter. The resulting slope of the second-order high-pass filter circuit is 40dB/decade (12dB/...
In order to achieve optimal saliency of the audio stimulus under these conditions, the audio signal was processed by a series of filters. First, a multi-band equalizer was used to implement a high-pass filter (−40 db attenuation in the 50 Hz band and −5 db at 100 Hz) to remove ...

So, in the spirit of promoting a genuinely useful public good which I can't believe almost nobody I talked to knew existed, if you're interested in finding a grant to fund your project, check out the KarmaGAP funding map for a comprehensive list of grants with filter and search tools,...
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 ...
using extensions of the work by Holy & Guo4, as well as high-pass filtered signal with a corner frequency of 10 kHz (4th order, Butterworth-filter), to prevent environmental noise from entering the estimate. All localization measures will be made available as a toolbox on our lab websit...
The dynamic hologram inside the crystal acts as a high-pass filter with a cut-off frequency 𝑓𝑐fc with a time constant 𝜏τ of the crystal (𝑓𝑐=1/(2𝜋𝜏)fc=1/(2πτ)). The cut-off frequency depends on the setup and is in the range of 3.5 and 10 kHzkHz for GaAs...
Mokhtari implemented wavelet de-noising and de-trending techniques in order to filter angular accelerations [26]. He proposed the Kalman filter method to preprocess the raw data to reduce noise [27]. Abbasi-Kesbi presented a method based on the L2-norm total variation (LTV) algorithm. The ...
