frequency band 英'friːkwənsɪ bænd美'friːkwənsiː bænd 短语²³⁵⁹⁵ 基本英英近义反义例句例句 n.频带;频段
Noun: a band of adjacent radio frequencies e.g., assigned for transmitting radio or television signals近义词 waveband波段 用作名词We use the term bandwidth to represent such a frequency range.我们用频带宽度这个词来代表这样的频率范围。 They are very compact in time and the frequency bands of interest are narrow.它们在时间上是非常紧致的同时有意义频带是狭的。 Each channel remains at an assigned frequency within a single band.每个信道在单一的频段内保持分配的频率。 We can't hear any program when we turn our radio onto thisfrequency band.当收音机调到这个频段上时,什么节目也收听不到。 The MIMO systems use multiple antennas at both the transmitter and receiver to transmit signal in the same frequency band at the same time can significantly increase the channel capacity. MIMO系统在发送端和接收端利用多个天线同时在相同的频带内传输信号,使得信道容量得到很大的增加。 cnki Based on the feedback correction law of the auto- control principle, analyses the use of negative feedback and it's deep amplifier which improves spreading frequency band's functions of amplifier. 本文通过自动控制原理中的反馈校正法对负反馈放大电路中引入负反馈改善放大器性能的展宽通频带和深度负反馈放大器进行了分析。 cnki |
