转换器

The relationships of signal-to-noise ratio of sampled signal, analog filter before analog-to-digital converter and sampling rate have been discussed, the results of the discussion have instructiveness for the design of digital receivers.

该文讨论采样后信噪比与模数转换器前的模拟滤波器以及采样率之间的关系，所得结论对数字接收系统设计有指导意义。

In this case, it need protocol converter to interconnect different buses.

这种情况下，就需要利用协议转换器使不同总线之间互联。

A low-power dissipation keyboard in portable measuring instrument, based on A/D converter method, is proposed in this paper.

摘 要 本文提出了便携式测量仪器中基于A/D转换器的低功耗键盘的设计方案。

The time sequence was used to drive the CCD.This driving circuit of CCD was not only used by lignum automatic measurement but also by others CCD.

对于CCD输出信号，可以根据CCD像素频率和输出信号幅值来选择合适的模数转换器；而对于C

In AC parameters measurement with high accuracy, as a rule, log and antilog amplifier is used to perform true rms-to-dc conversion.

在高准确度的交流参数测量中，对数-反对数放大器通常用来实现交直流真有效值转换器。

In this topology, the main switches are operated under ZVS due to commutation of the transformer magnetizing current and the parasitic drain-source capacitance.

在此转换器，其主要开关主要是利用变压器的激磁电流和开关本身内部的寄生电容的换向，使得主开关操作於零电压的模式底下。

An enterprising thief in a crowded parking lot or garage can make off with enough converters to clear $2,000 or $3,000 in half an hour.

在车辆众多的大型停车场或是车库，一个惯偷可以在半小时内偷走价值2000到3000美元的转换器。

Key words: time to digital converter , dead time effects , time of flight mass spectrometer

要害词：时间-数字转换器，死时间效应，飞行时间质谱计

To support these clock rates, a reasonable solution is to clock the ADC and DAC at a fixed master clock rate and perform sample rate conversion completely in digital domain.

为了支援这些标准，比较合理的作法是让类比转数位和数位转类比转换器工作在固定的频率，利用数位的作法改变取样频率以支援不同的通讯协定。

The third matcher is for displaying the form, and uses the Forms Template Transformer.

第三的匹配器用来显示表单，使用表单模板转换器。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
