active filter การใช้

• From 2008 to 2010 indirect ozoning and carbon active filters station were built.
• It is primarily used in active filter design and miniaturization.
• An "'active filter "'is a type of analog electronic filter that uses active components such as an amplifier.
• This consideration matters only with reactive and active feedback networks, as may be the case with active filters.
• An active filter was built into the Vanguard's modulator by Rick Jenkins, to avoid exceeding the allotted bandwidth.
• Analog IC design is used in the design of op-amps, linear regulators, phase locked loops, oscillators and active filters.
• In the standard it is said that the 33.06 nF capacitor may be adjusted or an active filter may be used.
• I know about LCD based active filters, and various aspects of polarized filtration, neither of which are exactly what I'm interested in.
• Furthermore, the advent of active filters eased the computation difficulty because sections could be isolated and iterative processes were not then generally necessary.
• Hooper's research and teaching experience was mainly in the area of transistor theory and characterization, pulse-forming circuits, wide band amplifiers, active filters and integrated circuit design.
• _A preservation product called Microchamber boxes, available through archival supply catalogs, features a chemically active filter that traps the acids in the frame of the box.
• Two other harmonics mitigation techniques exploit use of passive or active filters connected to a common bus with at least one VFD branch load on the bus.
• Applications include adjustable speed drives ( ASD ), uninterruptable power supplies ( UPS ), active filters, Flexible AC transmission systems ( FACTS ), voltage compensators, and photovoltaic generators.
• In combination with a reactor or choke coil, the electrical generator also works as active filter for all sorts of power quality problems, like harmonics, RFI, and frequency variations.
• Comer's areas of interest include passive and active filter design, MOS amplifier design, wideband amplifier design, operation of MOS stages in the weak inversion region, and high-speed chip-to-chip communications.
• The most common use for Food Grade synthetic magnesium silicate is as an active filter aid for adsorption of color, free fatty acids and other polar compounds from used frying oils.
• These can be " implemented " as analog circuits ( for instance, using a Sallen Key filter topology, a type of active filter ), or as algorithms in digital signal processing systems.
• These filters can be passive LC filters or active filters, consisting of an amplifier coupled through transformers and protection capacitors, which gives a signal out of phase to the interference signal on the line, thereby cancelling it.
• Each trait ( high pas / low pass / notch / boost ) of a desired active filter requires an op amp, active pickups do not include the 5-10 op amps required to accomplish most of what advertisers claim.
• Unlike models based on a series of active filters or represented with digital equations, an analog ear can incorporate nonlinearities that represent nonlinear actions of the basilar membrane, perhaps caused by asymmetric motions of sensory cells resulting in asymmetric motions of the basilar membrane.
