通频带 meaning in Chinese

[电学] passband

This reduces gain but widens the amplifier's passband .
这方法降低了增益，但加宽了放大器的通频带。
There is always a smooth transition between passband and stopband
通频带和抑止频带之间总是存在一个“平滑切换点” 。
But the bandwidth of the raw radar video is too wide to transmit directly in the common communication channel
但是雷达原始视频信号频谱很宽，要求传输设备有很宽的通频带，而且效率低、投资大。
Switching power amplifier is popularly used because of its virtues of low power losses , high efficiency and high frequency bandwidth
开关型功率放大器因其损耗小、效率高、通频带宽等优点，广泛取代了早期低效率的线性功放，成为目前功率放大器研究的重点。
In the future it may be possible to have such bandpass sigma - delta adcs with userprogrammable digital filter coefficients , so that the passband of a receiver could be modified during operation in response to the characteristics of the signal ( and the interference
未来可能会出现用户可编程数字滤波系数的带通- adc ，这样接收机的通频带就可以随着所接收的信号的特性而改变。
