transmission frequency bandwidth

A voice-grade transmission facility with defined frequency response, gain and bandwidth.

信道是指一种话音级传输设备,定义了频率响应 、 增益和带宽.

When the measured signal has a very wide frequency chart especially in the fast signal measurement field, in order to easily satisfy the high fidelity requirement that Bandwidth of Long Transmission Line, it is necessary for expanding the Bandwidth of Long Transmission Line.

当被测量信号具有很宽的频谱，尤其是在快脉冲信号测量中，为了测量数据在传输过程中满足高保真度的要求，必须对远距离传输线进行带宽扩展。

This paper reports the theoretical study on the transmission efficiency, bandwidth and frequency shift of anomalous dispersion atomic optical filter with off axis incident beam.

本文首次对反常色散原子滤光器在斜入射（0～π/2）条件下的透过率、带宽和频移等特性进行了理论研究；

However, poor conditions of transmission, serious noise background, time and frequency selective fading, the limited bandwidth of channel result in serious distortion of UWA communication signals.

但由于水声通信传输条件恶劣，存在严重的噪声背景，并且水下声信道的带宽十分有限，再加上复杂的多径传播和时间、频率选择性衰落，导致水声通信信号严重畸变。
