带宽

With the rapid development of broadband wireless network technology, the problem of bandwidth is not any longer the choke point.

摘要随着宽带无线网络技术的飞速发展，在宽带无线网络中的带宽问题已经不再成为瓶颈，从而促使宽带无线网络上的各种业务向着实时的趋势发展。

The basic video bandwidth required to transmit luminance and chrominance signals is 4/2 MHz for the NTSC standard.

NTSC标准中亮度信号和色度信号传输所要求的基本视频带宽是4.2MHz。

The device parameter as well as resonance frequency,mechanical quality factor and work band width were determined by the equiv- alent circuit input impedance admittance circle diagram .

分析压电式超声波换能器的等效电路，并由等效电路输入阻抗的导纳圆图确定了换能器的元器件参数以及谐振频率、机械品质因数和工作带宽等特征参量。

A analytical expression of spectral bandwidth is obtained through retaining term of first order(when expanding circular frequence of wave vector in Taylor series).

利用该解析式，采用数值计算的方法，分别研究了带宽随信号光波长、抽运光波长和非共线角的变化规律。

HDTV uses the entire digital bandwidth and is the crystal clear format you've probably seen on TVs in electronics stores.

高清晰度电视采用全数字化和带宽是晶莹剔透的格式，你可能看到的彩电企业在电子商店。

This is because the bandwidth required for a lot of time, CPU can only wait until the next clock cycle will be needed, because memory could not keep pace with CPU frequency.

这是由于当对带宽的需求很大的时候，CPU只能够等待下一个时钟周期才能够得到所需要的数据，因为内存的速度跟不上CPU的频率。

The experimental results show that it achieves peak SNR of 80 dB, peak SNDR of 78 dB and dynamic range of 84 dB over a 1 MHz signal band-width when clocked at 128 MHz. It dissipates 9 mW from a 1.8 V supply.

芯片工作在1.8V电源电压和128MHz时钟频率，在1MHz的信号带宽内，调制器的动态范围为84dB，峰值SNR和SNDR分别为80dB和78dB，功耗为9mW。

A common low-cost, internally frequency-compensated op amp is chosen; it has the required bandwidth at a closed-loop gain of 10, and it would seem to meet the bill.

选择一个普通的带有内部频率补偿的低价运放，它在闭环增益为10时具有所要求的带宽，并且看起来满足了价格要求。

As network bubble economy undone, the website visits a quantity gradually melt into " cloud drift ", in the meantime, tall visit quantity makes cost of server, bandwidth flying increase.

随着网络泡沫经济的破灭，网站访问量逐渐化为"浮云"，同时，高访问量使得服务器、带宽成本飞速增加。

It s found that wavelet transform is similar to the frequency response of cochlea, since both of them are proportional bandwidth filters.

经分析发现，小波变换是对人耳蜗频率响应的近似，二者都是一组比例带宽滤波器。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.

提出了用测地线方程、曲面上两点间短程线来计算膜结构曲面测地线的方法，同时，采用测地线间垂线的中点连线和用无约束极值法进行空间条状曲面近似展开的分析。
