随着21世纪计算机网络、通讯传输等技术的迅猛发展，调频广播信号发射技术逐渐成熟，对发射信号各项质量指标的要求也越来越高。作为传统的调频发射技术，非固态化发射机、模拟音频技术与低自动化程度设备已经无法满足不断发展的调频广播信号发射技术的要求。随着性能、技术指标、可靠性和价格占绝对优势的固态调频发射机的研发推出，它的地位逐渐取代了原先的电子管式。模块化的设计使得各种故障的排查都更为方便，系统整体运行稳定性也更加提高。而具有信噪比高、失真小、动态范围大等优点的数字音频信号克服了原先模拟音频技术中机械传输抖动、媒体本地噪声及非线性失真等缺陷，能大大提高信号传送的质量。而提高系统自动化程度，能有效减轻人...With the developing of computer network, and the technology of communication transmission etc, the technology of signal transmission for frequency modulation broadcasting becomes guadually maturer, the request for every quality standard of transmitting signal is more and more higher. As traditional transmitting technologies of frequency modulation, non-solid state transmitter, simulation audio tec...学位：工程硕士院系专业：信息科学与技术学院自动化系_控制工程学号：X200522302
