（3）器件选择

A：阻容元件的选择。不同的电路对电阻和电容性能要求也不同，有些电路对电容漏电要求很严，还有些电路对电阻、电容的性能要求很高，如滤波电路中常用大电容，100~3000uf铝电解电容，高频滤波常用小容量0.01~0.1uf瓷片电容。并要注意功耗、容量、频率和耐压范围是否满足要求。

B：分立元件的选择 包括二极管、晶体三极管、场效应管、光电二极管、晶闸管等是NPN型、PNP型、高频管、低频管、大功率、小功率管等，以及Pcm、Icm、Ft、 截止频率、特征频率。

C：集成电路的选择 由于 集成电路可以实现很多单元电路甚至整机电路的功能，所以选用集成电路设计单元电路和总体电路既方便又灵活，它不仅使系统体积小，而且性能可靠，便于调试及运用，在设计电路时颇受欢迎。集成电路有模拟集成电路和数字集成电路。国内外已生产出大量集成电路，器件的型号、原理、功能、特性可查阅有关手册。选择的集成电路不仅要在功能和特性上实现设计方案，而且要满足功耗、电压、速度、价格多方面要求。

比如一些典型的小规模门电路、触发器芯片，中规模的555定时器、计数器、编码器、译码器、施密特触发器、单稳态触发器、多谐振荡器等）等。

4、电路图的绘制

（1）布局合理、排列均匀、图面清晰、便于看图、有利于对图的理解和阅读。 （2）注意信号的流向，一般从输入端或信号源画起，由左至右或由上至下按信号的流向依次画出各单元电路，而反馈通路的信号流向则与此相反。

（3）图形符号要标准，图中应加适当的标注。图形符号表示器件的项目或概念。电路图中的中、大规模集成电路器件，一般用方框表示，在方框中标出它的型号，在方框的边线两侧标出每根线功能名称和管脚号。

（4）连接线应为直线，并且交叉和折弯应最少。一般不画斜线。互相连通的交叉线，应在交叉处用圆点表示。

5、了解电子器件结构、命名方法及工艺特点， 工艺技术规范，简单的制版、焊接、调试工艺过程，掌握常用电子仪器的使用方法。

6、设计的电路是否能满足设计要求，还必须通过组装、调试进行验证。 注：条件允许的话，尽量要求学生给出设计方案并在数字逻辑实验箱上搭接电路实现正确显示计时过程。

四、设计流程：

1、选题并由指导教师简要介绍题目内容；

2、分析题意，根据设计要求，查阅相关资料；提出理论设计方案，画出电路原理图； 3、根据已知条件及性能指标要求，确定电路及器件，计算电路元件参数，画出电路连线图，写出设计预习报告。

4、有条件到实验室将元器件安装在通用电路板，确认布线合理后再进行元器件的焊接。进行功能验证、

5、测试性能指标，调整与修改元件参数值，使其满足电路设计要求，将修改后的元件参数值标在设计的电路图上。

6、进行简单答辩并由指导老师给出答辩成绩. 7、编写设计说明书，写出规范的设计性报告。 8、上交设计说明书。由老师批阅后给出论文成绩。
