Phase-lock Demodulation of a PM Signal Contaminated with Incidental AM by George B. Robinson Pdf

Signals from phase-modulated satellite transmitters usually exhibit some degree of incidental amplitude modulation. The effects of incidental AM are analyzed when this type of signal is demodulated by a phase-lock receiver which does not employ a limiter preceding the loop phase detector. The presence of incidental AM causes a reduction in the receiver output signal-to-noise ratio. The tolerable level of AM decreases in proportion to the phase modulation index Beta. For a square-wave modulating signal, a 1 db reduction results at the receiver PM channel output when Beta = 1 radian and the percentage of AM = 23, Beta = 1.2 radians and the percentage of AM = 16, or Beta = 1.5 radians and the percentage of AM = 4. Although only the PM channel of the receiver is used ordinarily, utilizing both the AM and PM channel by summing offers an improvement in S/N relative to the S/N ratio of the PM channel if the percentage of incidental AM is greater than fifteen.

Phase-Locked and Frequency Feedback Systems by Jacob Klapper Pdf

Phase-Locked and Frequency-Feedback Systems: Principles and Techniques presents the operating principles and methods of design of phase-locked and frequency-feedback systems. This book is divided into 10 chapters that provide step-by-step design procedures and graphical aids, with illustrations bearing on real problems experienced in these systems. This work specifically tackles the application of these systems as FM demodulators with lowered thresholds. Chapters 1 and 2 deal briefly with the elements of linear systems, feedback theory, and noise, providing the minimum background for the material presented in the remainder of the text. Chapter 3 describes the characteristics of the major components that comprise the loops and the performance of the conventional and multi-loop FM demodulators. Chapters 4 to 7 present the basic describing equations and design for the FM feedback (FMFB) and phase-locked loop (PLL). These chapters further illustrate step-by-step design procedures with performance characteristics for low-threshold angle demodulation using typical design examples. Chapter 8 highlights the design principles, which are extended to the design of advanced demodulators featuring demodulation thresholds lower than those of the simple PLL or FMFB. Chapter 9 focuses on digital FM demodulation and PLL applications other than FM demodulation. Lastly, Chapter 10 presents the methods of testing and evaluating loop performance. Undergraduate and graduate level students, as well as practicing engineers, will find this book invaluable.
