摘要
从实践出发研究了综采工作面语音系统噪声的主要来源;针对不同应用需求,对滤波器的设计给出参考意见,并设计了带通有源滤波器;分析了声场分布对设备安装的要求、平衡信号和非平衡信号的选用及相应的抗干扰措施。
Major sources of noise in audio system of fully mechanized working face were researched in the practice. Advices of design of filter were given for different application requirements, and band-pass active filter was designed. Requirements of sound field distribution to equipment installation, selection of balanced and unbalanced signals and corresponding interference measures were analyzed.
