Examples of low-pass filters Acoustic A stiff physical barrier tends to reflect higher sound frequencies, and so acts as a low-pass filter for transmitting sound. When music is playing in another room, the low notes are easily heard, while the high notes are attenuated.Electronic In an ...
However, the filter proposed in [1], although one-dimensional, is implicit and increases considerably the CPU-time. In order to overcome this, the present work proposes a new three-dimensional, explicit, low-pass Laplace-filter which is numerically efficient, shows very good scaling features and...
Hence, it appears that a low-pass filter could easily address this issue. However, it is noted that these so-called high-frequency interferences only appear in the high-frequency domain when the pile dimension (radius) is small or the shear wave velocity of the pile material is high. As ...

As shown in Figure 59, K is the constant of proportionality relating the voltage across the IR sensor (VIN) to the radiation intensity, I. The resistances RA and RB are selected to provide a high gain to amplify this voltage, while CF is added to filter out the high frequency noise. ...
Families of 2D arrays can be constructed where each array has perfect autocorrelation, and the cross-correlation between any pair of family members is optimally low. We exploit equivalent Hadamard matrices to construct many families of p p × p arr

2. Proposed Filter Solution 2.1. Principle of Operation The transfer function of the second-order low-pass filter (biquadratic) expressed in the Laplace domain is as follows: 𝐻(𝑠)=𝑉𝑜𝑢𝑡(𝑠)𝑉𝑖𝑛(𝑠)=𝐴⋅𝜔20𝑠2+𝑠𝜔0/𝑄𝐿𝑃+𝜔20H(s)=Vout(s)Vin...
F and G represent the spatial domain filter centered on (x, y) and the value domain filter centered on (x, y), respectively. 𝜎𝑑σd is the standard deviation of the spatial domain, which is used to adjust the weight values of pixels with larger spatial distances. 𝜎𝑟σr is ...
Other sensorless techniques exploiting the zero-sequence voltage for induction motors have been proposed in [14], where a filter has been tuned for distinguishing between the rotor bar and the magnetic saturation effects, in [15], where a technique to reduce noise given by cables has been also...
