phase control
11Phase detector — A phase detector is a frequency mixer or analog multiplier circuit that generates a voltage signal which represents the difference in phase between two signal inputs. It is an essential element of the phase locked loop (PLL).Detecting phase… …
12Phase margin — In electronic amplifiers, phase margin is the difference, measured in degrees, between the phase of the amplifier s output signal and 360°. In feedback amplifiers, the phase margin is measured at the frequency at which the open loop voltage gain… …
13Control of chromosome duplication — A key feature of the DNA replication mechanism in eukaryotes is that it is designed to replicate relatively large genomes rapidly and with high fidelity. Replication is initiated at multiple origins of replication on multiple chromosomes… …
14Control of the National Grid — The National Grid is the high voltage electric power transmission network in Great Britain, connecting power stations and major substations, and has a synchronized organization such that electricity generated anywhere in Great Britain can be used …
15Phase-shift keying — Passband modulation v · d · e Analog modulation AM · …
16Phase space — In mathematics and physics, a phase space, introduced by Willard Gibbs in 1901, is a space in which all possible states of a system are represented, with each possible state of the system corresponding to one unique point in the phase space. For… …
17Phase response curve — A phase response curve (PRC) illustrates the transient change in the cycle period of an oscillation induced by a perturbation as a function of the phase at which it is received. PRCs are used in various fields; examples of biological oscillations …
18Phase shift module — A phase shifter is a microwave network which provides a controllable phase shift of the RF signal [Microwave Solid State Circuit Design, 2nd Ed., by Inder Bahl and Prakash Bhartia, John Wiley Sons, 2003 (Chapter 12)] [RF MEMS Theory, Design and… …
19Control theory — For control theory in psychology and sociology, see control theory (sociology) and Perceptual Control Theory. The concept of the feedback loop to control the dynamic behavior of the system: this is negative feedback, because the sensed value is… …
20Control-Feedback-Abort Loop — Too often systems fail, sometimes leading to significant loss of life, fortunes and confidence in the provider of a product or service. It was determined that a simple and useful tool was needed to help in the analysis of interactions of groups… …
