Round brackets are used to segment algorithms to assist memorisation and group move triggers. Moves in square brackets at the end of algorithms denote a U face adjustment necessary to complete the cube from the states specified. It is recommended to learn the algorithms in the order presented.

A PLL is a feedback system that includes a VCO, phase detector, and low pass filter within its loop. Its purpose is to force the VCO to replicate and track the frequency and phase at the input when in lock. The PLL is a control system allowing one oscillator to track with another.
the PLL, this book focuses mainly on the use of a PLL to generate a stable output frequency. In this situation, the PLL starts with a fixed and stable input frequency and this is used to generate one or more output frequencies.
由于PLL反馈的信号通常是方波,大多数电路工作在开关状态,是典型的非线性系统。 精确分析PLL 的系统特性是比较困难的。 在PLL锁定时,可以近似认为是一个线性系统,简化分析。 不同阻尼系数所对应的频率响应如图所示,注意这里的频率是指信号相位的变化频率,区别于VCO信号的真实频率。 压的谐波(简单锁相环的最大缺陷)。 将使环路不稳定。 通常使 1/10 ,也就是( / 2π)<(f. 加入并联电容C。 但是只要保证. 也会出现短的重合脉冲。 但是如果重合脉冲过短,寄生电容将会使 …
What is a PLL? A PLL is a negative feedback system where an oscillator-generated signal is phase and frequency locked to a reference signal. How are PLL’s Used? is the focus of this tutorial. Power Supply regulator/filter (VREG)? Is My PLL Stable? PLL is 2nd-order system similar to mass-spring-dashpot or RLC circuit.
Phase-locked loops can be used, for example, to generate stable output high frequency signals from a fixed low-frequency signal. Figure 1A shows the basic model for a PLL. The PLL can be analyzed as a negative feedback system using Laplace Transform theory with a forward gain term, G(s), and a feedback term, H(s), as shown in Figure 1B.

Each PLL loop works as a feedback system shown in Fig. 1. To get more insight into the PLL properties, we shall simplify, without any loss of generality, the block diagram to that shown in Fig. 2. and introduce the Laplace transfer functions of the individual building circuits - suitable for investigation of small signal properties.
