Sentence examples for lower cutoff frequency from inspiring English sources
The second filter (LPF2) is designed to improve the suppressing level of the LPF1 with a lower cutoff frequency.
Throughout the paper, we will consider a finite upper cutoff frequency and a non-vanishing lower cutoff frequency.
By choosing the capacitors C4, C5 and the resisters R5, R7, we can adjust the lower cutoff frequency of the preamplifier.
From Eqs. (36) and (37) it can be seen that for a vanishing lower cutoff frequency of the independent noise spectrum, the variance diverges and as a consequence of this the cross-correlation between the two spike trains vanishes only the part that is due to the signal (second term in Eq. (37)) still contributes.
A model (Anderson and Hough 1984) characterized the shape of FAS at high frequencies, shown as a(f) = A_{0} exp left( { - pi kappa f} right)quad {text{for}},f > f_{text{e}}, (7 where A 0 is a source and propagation path-dependent amplitude and f e is the lower cutoff frequency above which the decay of FAS can be considered as approximately linear observed in a log-linear space.
To simplify the analysis, we assume that the BPF is an ideal filter with a lower cutoff frequency of f L and an upper cutoff frequency of f H, respectively, and the pulses in v t) to be rectangular with duration t w. Figure 2 b shows the FP pulse with amplitude A (A>0 when it is a positive pulse, or A<0 for a negative pulse), rising edge at t r, and falling edge at t f, where t f −t r =t w.
The upper and lower cutoff frequencies are indicated by dashed lines.
The dashed lines are the upper and lower cutoff frequencies of the passband filter.
These highpass values are then scaled to give a new cutoff frequency, W. The new cutoff frequency must be made equal to the difference between upper and lower cutoff frequencies for the desired bandstop filter.
We show theoretically that the upper and lower cutoff frequencies of the guided band in a 2D photonic crystal coupled-cavity waveguide can be controlled independently or synchronously by changing two configuration parameters of the waveguide simultaneously.
Shankar et al. used the black body as simulated radiation sources of the human body and found that the upper and lower cutoff frequencies of the sensor is 0.7 and 2 Hz, respectively, [25].
