  • [电学] passband

例句与用法

  • 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。
  • Combined with researches on propagation characteristics , the micro - current sensor for on - line pd monitoring is developed and the effects of coil number , stray capacitance and loading resistance on pass - band and sensitivity are also studied
    同时,结合传播特性,研究了局部放电在线监测宽带微电流传感器,并就线圈匝数、杂散电容和负载电阻等对传感器通频带、灵敏度等性能参数的影响进行了分析。
  • Secondly the detection precision is only related to the synchronization phase but not to the amplitude of the mainline voltage because that it uses the optimized pulses synchronous with the mainline voltage as modulation signals . thirdly it decreases the requirement of the input low pass filter and eliminates the error resulting from the direct component and even harmonics of load current . the most significant merit is that it can eliminate the effect of a few low order odd harmonics and the detecting circuit is easy to be implemented
    仿真和实验结果表明该方法的主要优点有:不需使用乘法器进行信号调制,调制信号采用与电网电压同步的优化特定脉冲,其检测精度只与同步相位有关,而与电网电压幅值无关;降低了对输入低通滤波器的通频带要求,直流和偶次谐波分量对检测精度没有影响;突出的优点是可以消除有限个低奇次谐波对检测结果的影响。
