音频振荡器是无线电测量、声学和电磁学测量、自动化技术以及遥控遥测等方面应用十分广泛的仪器。在声音广播和电视广播方面也是最常用的测量仪器之一。由于科学技术的迅速发展,在声音广播和电视广播设备方面新产品新技术不断出现,产品质量也不断地改进提高。在一些工业较先进的国家,声频设备方面都已晶体管化,也有的部分的或绝大部分的集成化了。国内在这方 Audio oscillators are a wide range of instruments for radio measurement, acoustic and electromagnetics measurements, automation technology and telemetry. It is also one of the most commonly used measuring instruments in sound broadcasting and television broadcasting. Due to the rapid development of science and technology, new products and new technologies are continuously appearing in sound broadcasting and television broadcasting equipment, and product quality is constantly improving and improving. In some of the more advanced industrial countries, audio equipment has been transistor-based, and some or most of the integration. Domestic in this side
