电子电路的设计基本步骤:
1、明确设计任务要求:
充分了解设计任务的具体要求如性能指标、内容及要求，明确设计任务。
2、方案选择:
根据掌握的知识和资料，针对设计提出的任务、要求和条件，设计合理、可靠、经济、可行的设计框架，对其优缺点进行分析，做到心中有数。
3、根据设计框架进行电路单元设计、参数计算和器件选择:
具体设计时可以模仿成熟的电路进行改进和创新，注意信号之间的关系和限制;接着根据电路工作原理和分析方法，进行参数的估计与计算;器件选择时，元器件的工作、电压、频率和功耗等参数应满足电路指标要求，元器件的极限参数必须留有足够的裕量，一般应大于额定值的1.5倍，电阻和电容的参数应选择计算值附近的标称值。
4、电路原理图的绘制:
电路原理图是组装、焊接、调试和检修的依据，绘制电路图时布局必须合理、排列均匀、清晰、便于看图、有利于读图;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务单元电路，反馈通路的信号流向则与此相反;图形符号和标准，并加适当的标注;连线应为直线，并且交叉和折弯应最少，互相连通的交叉处用圆点表示，地线用接地符号表示。你可以参考一下，希望我的回答能帮到你。

1、国外厂家生产或在国内合资生产的，典型代表有梅特勒－托利多电子秤，赛多利斯电子天平等
2、台系厂商或在国内合资生产，典型代表是樱花电子秤，英展电子秤，钰恒电子秤，
3、国产品牌电子秤，主要看具体产地，多分布在上海，江苏常州，浙江永康，福建，广东等地。电子秤价格方面，国外厂家如梅特勒－托利多电子秤价格相对来说偏高，相同功能情况下，一般为国产电子秤价格3－10倍，看重价格因素的客户不建议选购。
4、台系列品牌电子秤相对来说，价格较为适中，品质稳定，电路设计水平较国产电子秤稍高一筹，故电子秤使用寿命较国产要长2－3年，综合性价比更高。国产品牌电子秤相对来说，要比台系列电子秤价格低30%左右，首次购买成本更低，但因为使用寿命较短，综合性价比稍差。说了这么多，电子称什么牌子好，相信你已经擦亮那双慧眼了。我们推荐您使用樱花电子秤，英展电子秤，好用，价格实惠，质量稳定。希望我的回答能帮到您
