比例放大器 meaning in English
proportional amplifier
ratio amplifier
Examples
- With the development of the ratio system , the proportional amplifier develops constantly as the control equipment
而作为比例电磁铁的电控设备，比例放大器一直是随着比例系统的发展而发展的。 - Because of signal proportional valves with the ratio between the need to install dc amplifier , a corresponding increase in investment costs
由于在输入信号与比例阀之间需设置直流比例放大器，相应增加了投资费用。 - But homemade ratio amplifier still stays the base of step control . the stepless controlling amplifier always depends on the import
但国内在开发比例放大器方面一直停留在档位式调节基础上，具有连续调节式的比例放大器多依靠进口。 - The proportional valve " natural work depends on the accurate setting of the ratio amplifier . so the work parameter must be set before the running of the valve
由于比例放大器与比例阀是一一对应的关系，比例阀的正常工作很大程度上是依靠对比例放大器的准确设定，所以比例放大器中各调节指数都需要经过测试。 - Firstly , the theory and the architecture of hardware system are described , secondly , the steps of the signal processing are discussed in detail . based on the experiments and the characteristics of the signal , we pre - process the signals with band - pass filter , proportional amplifier and coherent demodulator . after sampling and analysis doppler information , we display the final results distinctly to alarm in time
然后，结合系统中各主要部分的任务，详细介绍了信号处理的各个步骤：通过实验比较，并结合接收信号的特点，选用带通滤波器、比例放大器、相干检波等技术对信号进行预处理；然后对获得的多卜勒信息进行采样和频谱分析；最后，用比较直观的形式显示数据结果，以及时准确地告警。
