frequency synthesizerの例文

• Many PLL frequency synthesizers can also generate frequency modulation ( FM ).
• Frequency multipliers are often used in frequency synthesizers and communications circuits.
• Many types of frequency synthesizer are available as integrated circuits, reducing cost and size.
• Multiple channels are often provided using a frequency synthesizer.
• In recent years, the company has begun to develop frequency synthesizers and low-power wireless modules.
• A modern digital synthesizer uses a frequency synthesizer microprocessor component to generate signals of different frequencies.
• This is called a frequency synthesizer.
• One of the latest to reach our shores is a face massage machine called the Radiance Micro Frequency Synthesizer.
• Engineers recognized that newer aircraft radios already included all-channel frequency synthesizers along with keyboards and displays for data entry.
• Measures such as spurious-free dynamic range are used to quantify the dynamic range of various system components such as frequency synthesizers.
• PLLs may include a divider between the oscillator and the feedback input to the phase detector to produce a frequency synthesizer.
• Phase-locked loop frequency synthesizers make use of frequency dividers to generate a frequency that is a multiple of a reference frequency.
• The LO signal is generated by a Gunn diode oscillator whose frequency is controlled via a phase-lock loop system by a computer-controlled frequency synthesizer.
• The key to the ability of a frequency synthesizer to generate multiple frequencies is the divider placed between the output and the feedback input.
• Thus, in a PLL frequency synthesizer there are two buses, one for the reference counter, the other for the output ( or VCO ) counter.
• In practice this type of frequency synthesizer cannot operate over a very wide range of frequencies, because the comparator will have a limited varactor diodes.
• Their disadvantage is that changing frequency ( more than a small amount ) requires changing the crystal, but frequency synthesizer techniques have made this unnecessary in modern designs.
• His doctoral dissertation on " Architectures, Optimization Techniques, and VLSI Implementations for Direct Digital Frequency Synthesizers " became the basis for the development of the chip that launched Broadcom.
• In the 1970s, receivers began to be designed using frequency synthesizer circuits, which synthesized the receiver's input frequency from a crystal oscillator using the vibrations of an ultra-stable quartz crystal.
• With the advent of digital frequency synthesizers that could be set with high resolution by a keypad or incremental tuning knob, the requirement for bandspread control in many applications was eliminated.
