简单低通滤波器:Simple Low-pass Filter The simple low-pass filter is shown in Figure 11. This circuit has a 6 dB per octave roll-off after a closed-loop 3 dB point defined by fc. Gain below this corner frequency is defined by the ratio of R3 to R1. The circuit may be considered as...

We studied the characteristics of a two-dimensional grating optical low-pass filter (GOLF) theoretically and experimentally. The modulation transfer function (MTF) of an optical system that consists of a lens and a GOLF is theoretically derived by taking all orders of diffracted beams into considera...
A simple technique for designing low-pass recursive digital filters with nearly linear phase characteristic is presented. The linearity of phase is obtained by placing the poles in the neighbourhood of the passband at equal intervals on a circle of radius r, inside the unit circle on the z-plan...

The image was obtained using a confocal fluorescence microscope (Olympus IX81, Objective, x100, NA 1.4), a 485 nm excitation laser line and a low pass filter with 500 nm cut-off wavelength. The field of view of the image in the left panel of Fig. 8 is 30 by 30 \(\mu \)m\(^2...
(up to 1.6 kHz as default value). It is partly because of spectral character of tested sounds, talking, clapping, etc. Sensitivity of the device has been set above common sound levels such as voice signals. Moreover, the bandwidth of the low-pass filter can be easily modified for ...
This model gives rise to a simple preview balance controller consisting of a four-term control law with easily calculated gains and a reverse-time low-pass filter acting on a preview of the command signal. The filter makes the robot lean in anticipation of future move- ments. Simulation ...
You'll need to run the pin through a low-pass filter to remove the noise, and connect it to an amplifier as the GPIO pin won't really supply much current. Launchpad PinTiva-C PinTRSFunction J1.5PE4Ring/TipAudio Left J1.6PE5TipAudio Right ...
It is possible that this problem may be alleviated by allowing the UGM’s low-pass filter to have a very long time constant, making its evidence accumulation process less leaky, and more like the diffusion model. We explored this possibility by fitting the UGM with the time constant as a ...
