The wide frequency bandwidth, big gain, and high out put power were required.
该功放具有工作频带宽，增益大，输出功率高等特点。
Therefore; to expand the frequency bandwidth and to remain the same sensitivity is difficulty.
因此，欲展宽频带而保持灵敏度不变就很困难。
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。
Video bandwidth is not the frequency range over which the instrument itself can accept signals;
视频带宽不同于仪器本身接受信号的频率范围；
Video bandwidth is not the frequency range over which the instrument itself can accept signals;
