说明：   接收设备能对外界信息正确的接收、分析、处理的重要性是不言而喻的,它关系到社会的发展、人类的进步。然而在有用信号中往往伴随着噪声的存在。这种噪声分为电路内部固有的噪声与系统装置从外部接收而来的噪声。电路内部的噪声是系统固有的，与外界干扰无关，它可以通过对电路的合理设计、选择合理的元器件而得以控制。外部噪声主要由近几年的电子技术的高速发展，电子、电气设备的广泛应用而带来的电磁干扰引起的。这种噪声现象在工业发达的城市非常突出，它对各种系统接收装置的影响也越来越严重，使得这些系统装置不能正常工作，使得这些系统装置性能降低，甚至使得这些系统装置受到损坏。战胜噪声已是现代电子技术发展道路上必须逾越的巨大障碍。要解决噪声带来的问题需要我们从最基本的干扰源、信息传输通道（信道）、系统装置电路下手。(The receiving device and system noise)
