软件编程实现多种音源报警

传统的集成电路报警音源电路简单，应用方便，但种类少，而用模拟器件构成的音源其电路复杂、频率不准确、调试难，已不能满足快速变化的市场需求。为了产生多种音源的目的，采用软件编程方法，做了编程仿真调试实验。实验结果表明报警声音选择和改变非常容易，频率稳定准确，具有适合于各种报警器生产厂家使用的特点。

Designing Many Kinds of Audio Source Alarm by Software Programming

The audio source alarm of the traditional integrated circuit is simple and convenient,while the audio source constituted by the analog devices can't meet the market requirement due to the complicate circuit,inaccurate frequency and complex debugging.For producing variety of audio source,a method of the software programming and a simulation program debug are performed.Experimental result shows that it is easy to select and alter the alarm sound,the stable and accurate frequency can be gained.It is suitable f...
