Definition of "Frequency Synthesizer" |
A frequency synthesizer is an electronic circuit that uses an oscillator to generate a preprogrammed set of stable frequencies with minimal phase noise. Primary applications include wireless/RF devices such as radios, set top boxes, and GPS. / A frequency source of high accuracy. A device that produces frequencies that are phase coherent with a reference frequency. A bank of oscillators in which the outputs can be mixed in various combinations to produce a wide range of frequencies. / A frequency synthesizer is an electronic circuit that uses an oscillator to generate a pre programmed set of stable frequencies with minimal phase noise. Primary applications include wireless/RF devices such as radios, set top boxes, and GPS. / A frequency synthesizer is an electronic system for generating any of a range of frequencies from a single fixed timebase or oscillator. They are found in many modern devices, including radio receivers, mobile telephones, radiotelephones, walkie-talkies, CB radios, satellite receivers, GPS systems, etc. A frequency synthesizer can combine frequency multiplication, frequency division, and frequency mixing,the frequency mixing process generates sum and difference frequencies operations to produce the desired output signal. / Control of a machine or apparatus from a distance by means of radio or infrared signals transmitted from a device. / an oscillator that produces sinusoidal wave with arbitrary frequency. In common cases, generated frequencies are allocated with a frequency spacing called the channel step. |
