As a result, the cutoff frequency is the resonance frequency of this filter and according to combinations of logical levels of control signal n-infinity , n0 and n1 supplied to the circuit 11, the depth of resonance levels is controlled.NAKAZAWA KOUTAROU...

As a general principle, any properly overlapping high- and low-pass filters can be used to obtain a band-pass filter; band−pass(X(t))=high−pass(low−pass(X(t))) =low−pass(high−pass(X(t)))⋅ Band-pass filters are used, for example, wh...
CTCSS REJECT HIGH PASS FILTERS IN FM RADIO COMMUNICATIONS AN EVALUATION Virgil Leenerts WØINK 8 June 2008 The response of the audio voice band high pass filter is evaluated in conjunction with the rejection of the CTCSS tone frequencies. The dual function of this filter in FM radio co...
[B,A] = designVarSlopeFilter(___,Name,Value) Description [B,A] = designVarSlopeFilter(slope,Fc)designs a lowpass filter with the specified slope and cutoff frequency.BandAare matrices of numerator and denominator coefficients, with columns corresponding to cascaded second-order sections (SOS)....
(5, 3) filter requires multiplication of two filter coefficients,αandβ, whose values are -1/2 and 1/4, respectively. Coefficient multiplication is designed using logical left shift operation by one and two bits, respectively. We have used simple and power efficient hardwired scaling unit (...
Coefficients of GCaMP6f and tdTomato were unmixed by a customized script by fitting spectrum signals to standard emission curves. GCaMP6f signals were normalized by tdTomato signals for motion correction. (Supplementary Fig. 22a). A 0.1 Hz high-pass filter corrected the fluorescence bleaching....
High-pass filter based on a Poisson wavelet Φ at order m=3. The cutoff is ncut=100 and the wavelet scale is 0.03 Full size image To subtract the terrain effects included in EIGEN-6C4, we used the topographic potential model dV_ELL_RET2012 (Claessens and Hirt 2013) truncated at d/o ...
EWS are first searched for in terms of significant positive trends in the variance (σ2(t)) and lag-1 autocorrelation (α1(t)) of the 100-year high-pass filtered NGRIP data. Specifically, we apply a Chebyshev Type-I high-pass filter with cutoff at 100 years to the time series and...
