frequency multiplier การใช้

• Frequency multipliers are often used in frequency synthesizers and communications circuits.
• Merely changing the CPU core frequency multiplier will have an effect on scheduling.
• This element can be other elements such as a frequency multiplier, or a mixer.
• To get better resolution, a phase-locked loop frequency multiplier can be used to generate a faster clock.
• Sometimes the frequency multiplier circuit will adjust the width of the impulses to improve conversion efficiency for a specific harmonic.
• Frequency multipliers upconvert the light to green and blue ( UV ) just prior to entering the " target chamber ".
• Optical frequency multipliers are very common in high-power lasers, notably those used for inertial confinement fusion ( ICF ) experiments.
• Design started in the late 1970s, with construction following shortly starting with the testbed Novette laser to validate the basic beamline and frequency multiplier design.
• Phase modulators are typically only capable of relatively small amounts of deviation while remaining linear, but any frequency multiplier stages also multiply the deviation in proportion.
• In 2009, researchers built experimental graphene frequency multipliers that take an incoming signal of a certain frequency and output a signal at a multiple of that frequency.
• A solution to this problem was explored in the form of efficient frequency multipliers, optical devices that combine several photons into one of higher energy, and thus frequency.
• For example, if the phase locked loop were to implement a frequency multiplier, the oscillator signal could be divided in frequency before it is compared to the reference signal.
• This is typically addressed through the use of an optical frequency multiplier, which can double or triple the frequency of the light, into the green or ultraviolet, respectively.
• In this field varactor diodes are used as a voltage variable capacitor in frequency multipliers, parametric amplifiers and variable junction when reverse biased which is the source of the capacitor effect.
• The mixer circuit can be used not only to shift the frequency of an input signal as in a receiver, but also as a product detector, modulator, phase detector or frequency multiplier.
• In electronics, a "'frequency multiplier "'is an electronic circuit that generates an output nonlinear circuit that distorts the input signal and consequently generates harmonics of the input signal.
• It can be more economical to develop a lower frequency signal with lower power and less expensive devices, and then use a frequency multiplier chain to generate an output frequency in the microwave or millimeter wave range.
• ICF research turned to using an " optical frequency multiplier " to convert the incoming IR light into the ultraviolet at about 351 nm, a technique that was well known at the time but was not efficient enough to be worthwhile.
• An "'optical frequency multiplier "'is a nonlinear optical device in which photons interacting with a nonlinear material are effectively " combined " to form new photons with greater energy, and thus higher frequency ( and shorter wavelength ).
• At each step of the chain, a frequency multiplier would be used to produce a harmonic of the frequency of that step, which would be compared by heterodyne detection with the next step ( the output of a microwave source, far infrared laser, infrared laser, or visible laser ).
