摘要
介绍了采用8098单片机构成高性能多功能信号发生器的方法及硬件结构 ,以及利用RAM、数字频率合成器、DAC配合软件方式生成各种波形数据的方法 它是利用DAC将数字量转为模拟量生成多种模拟波形的 ,其目的是用它取代模拟电路信号发生器 ,这样就能使信号的频率范围覆盖低频和超低频 ,同时由于采用了单片机就使得该信号发生器具有计数、定量、重复。
This article gives an introduction to the way of making a high-quality and multi-founction signal generator by using a 8098 microcontroller as well as to the hardware structure of the generator. It also deals with how to use RAM, digital frequency synthesizer, DAC ,together with software to produce various wave data.The signal generator makes use of DAC to transfer digital signal into analogue signal so as to form various analogue waves. The purpose is to replace the signal generator of analogue circuits with that of high quality and multi-functions. Thus, the frequency range of signal can cover both low-frequency and intrasonic-frequency. Beside, due to the use of the microcontroller, the signal generator has such funcitions as counting, timing, reappearing and outputting.
