adjustable attenuator meaning in English
可单减器
可调衰减器
Examples
- Delay line oscillator is composed of broadband amprifer adjustable attenuator and saw sensor device . after output signal of delay line oscillator is smoothed , it mixes with 109mhz local oscillation signal . its differential frequency signal is smoothed by low - pass filter trimmed by shaping circuit and processed by digital processing circuit
延迟线振荡器由宽带放大器、可调衰减器和声表面波质量传感器件构成。延迟线振荡器输出信号经滤波后与109mhz的本机晶体振荡器输出信号相混频，通过低通滤波取其差频，并经整形后由数字信号处理电路处理。
