摘要
给出了一种新的基于数字信号处理器DSP(DigitalSignalProcessor)的有线电视伴音信号监控系统的设计方案 ,讨论了利用DSP的高速实时处理能力对多路音频信号电平进行反馈控制的方法 ,并就该系统的软。
Based on DSP(Digital Signal Processor), this paper gives a new plan to design for processing the audio accompanying sound level system of CATV, and discusses the method of antrolling multiline audio feedback signals,by means make use of DSP's processed ability with high speed and real-time. The designs of hardware and software in the system are also elaborated.
