| 摘 要： | 设计产生可预置幅度数据的模拟CCD输出的信号源数字系统，且此信号源模拟输出的幅度可通过外部拨码开关实时调整，并且设计了相应的时序信号。该系统数字部分主要利用拨码开关、单片机AT89C51，复杂可编程逻辑器件进行设计。软件分别用C51和VHDL语言编程，结构紧凑、体积小、拨码开关操作灵活。

| Abstract: | The signal generator is introduced and is used to produce a square wave, which is similar as the output of a CCD and could be set beforehand. The signal's scope could be easily adjusted through the data-chosen-switches in real-time. The system utilizes data-chosen-switches, microprocessor AT89C51 and complex logic device (CPLD).The software program is written by C language and VHDL language,respectively. The system construction is compact and the volume is sma1l, and the data-chosen-switch operation is flexible and convenient. |
