固定频率源可以在在通讯系统和雷达系统中作为本机振荡器，也可以作为数字电路的基准时钟信号，因此得到了广泛的应用。
Single frequency source is usually used as local oscillator in communication system and radar system, also as a reference clock in digital circuits, so it is a extensive-applied technique.

A frequency comparator compares the frequency of a reference clock with that of an output clock and outputs a frequency comparison signal.
在时域测量中，巧妙的借用“游标卡尺”原理，利用两种不同频率的时钟信号同时对信号时差进行精确测量，其测量精度较之传统的方法有很大的提高。
An improving measurement with the principle of the vernier caliper is presented, which USES the clock-signals with two different frequencies, and the precision is improved much.
总线时钟与处理器内核时钟频率不同，因此总线部件与处理器内核间的接口信号需要进行时钟域转换。
The bus and the processor core often run in different clock frequencies, so their interface signals belong to different clock domains.
相位频率检测器比较基准时钟信号和反馈时钟信号从而在一个或更多个输出信号中生成脉冲。
A phase frequency detector compares a reference clock signal to a feedback clock signal to generate pulses in one or more output signals.
当基准和反馈时钟信号的相位和频率相同时，PLL处于锁定模式，且PFD输出信号中不生成脉冲。
When the phase and frequency of the reference and feedback clock signals are the same, the PLL is in lock mode, and the PFD does not generate pulses in its output signals.
假设高信号使能，计数器每个时钟周期进行计数，PWM输出的频率为时钟频率的2次幂分频。
Suppose that Enable is high, the counter counts up every clock cycle, and the frequency of the PWM output is the clock frequency divided by 2 count bits.
时钟频率不再是性能的精确测量指标的第二个原因是，将时钟信号分配到芯片的不同部分，要比说说困难得多。
A second reason why clock frequency will no longer be an accurate measure of performance is that distributing the clock's signal to all the different parts of a chip is more difficult that it sounds.
其他的一些单片机有可能是和它相反的，在那里他们更像一个数字信号处理器，有更高的时钟频率和功率消耗。
Other microcontrollers may serve performance-critical roles, where they may need to act more like a digital signal processor(DSP), with higher clock speeds and power consumption.
