How to acquire the input frequency from an unlockedstate
A phase locked loop (PLL) by itself cannot become useful untilit has acquired the applied signal's frequency. Often, a PLL willnever reach frequency acquisition (capture) without explicitassistive circuits. Curiously, few books on PLLs treat the topic offrequency acquisition in any depth or detail. FrequencyAcquisition Techniques for Phase Locked Loops offers ano-nonsense treatment that is equally useful for engineers,technicians, and managers.
Since mathematical rigor for its own sake can degenerate intointellectual "rigor mortis," the author introduces readers to thebasics and delivers useful information with clear language andminimal mathematics. With most of the approaches having beendeveloped through years of experience, this completely practicalguide explores methods for achieving the locked state in a varietyof conditions as it examines:
* Performance limitations of phase/frequency detector-basedphase locked loops
* The quadricorrelator method for both continuous and sampledmodes
* Sawtooth ramp-and-sample phase detector and how its waveformcontains frequency error information that can be extracted
* The benefits of a self-sweeping, self-extinguishingtopology
* Sweep methods using quadrature mixer-based lock detection
* The use of digital implementations versus analog
Frequency Acquisition Techniques for Phase Locked Loopsis an important resource for RF/microwave engineers, in particular,circuit designers; practicing electronics engineers involved infrequency synthesis, phase locked loops, carrier or clock recoveryloops, radio-frequency integrated circuit design, and aerospaceelectronics; and managers wanting to understand the technology ofphase locked loops and frequency acquisition assistance techniquesor jitter attenuating loops.
