多谐振荡器

The conventional oscillator is often denoted as an astable multivibrator and has a duty cycle of approximately 50%.

传统振荡器通常表示为一个无稳态多谐并拥有约50％的工作周期。

Multivibrator This is used to complete the 555 timer.

而这个多谐振荡器采用的是555定时器来完成的。

The multivibrator is a switching circuit that toggles on and off continuously in response to an applied input voltage.

多谐振荡器是一个开关电路切换和关闭不断在回应一个应用的输入电压。

Finally, there is a part of the generated pulse Multivibrator Based on square wave can be generated, you can use it to generate a pulse signal.

最后还有一个部分就是脉冲的产生基于多谐振荡器可以产生方波，就可以利用它来产生脉冲信号了。

Multivibrator, simulation, using the three-tier governing structure, the electronic design has a certain significance.

详细说明：多谐振荡器，的仿真，采用三级管构成，对电子设计方面的人有一定的意义。

The system designed to break the traditional model, First of all, the measurement of the resistivity of components using parameters R consisting of 555 timer Multivibrator transformed into a frequency signal f, Then after counting SCM operations of the resistance R calculated, the final delivery of digital display circuit, the implementation of intelligent measurement.

该系统打破传统的设计模式，首先把要测量的电阻元件的参数R利用555定时器构成的多谐振荡器转换成频率信号f，然后用单片机计数后再运算求出R的阻值，最后送数码显示电路，实现了智能化测量。

In the former stage, Based on the concept that both glottal excitation and vocal tract parameters are time varying in amplitude and frequency, we detect pitch with frequency domain transform

在波形合成阶段，以基音频率轨迹为依据，将混叠语音信号分割为独立的短时周期信号，利用数字多谐振荡器的选频特性，获取相应的各次谐波的频率、幅度以及相位信息，利用这些参数在频域叠加来合成

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
