AN-0 Coconut EMC整改案例是针对一款产品——椰子(可能是设备或软件的代号)在电磁兼容(Electromagnetic Compatibility, EMC)测试中的问题解决方案文档。文档作者Andy Chou来自深圳的深信服科技公司,地址位于南山智园A1栋。主要内容分为两部分:测试结果分析和整改策略。 1. **测试结果**: - **辐射超标**:文档首先揭示了在测试过程中,椰子产品在辐射方面存在超标的问题,这可能导致对无线通信环境的干扰或者不符合电磁辐射标准,可能涉及射频(RF)泄漏或其他辐射源的问题。 - **静电**:除了辐射,文档还提及了静电防护问题,这可能指设备在操作过程中产生的静电可能会引发敏感电路故障或干扰其他电子元件。 - **浪涌**:浪涌保护也是检测的一部分,可能是指产品在电源电压突然变化时的性能受到影响,可能需要增强抗扰能力以确保设备正常运行。 2. **整改对策**: - **问题定位**:首先对超标问题进行了深入分析,通过数据和测试结果来确定具体是哪个环节或组件导致的电磁兼容性问题。 - **RC参数选择**:文档中提到了选择合适的电阻(R)和电容(C)参数进行整改,这是常见的解决EMC问题的方法,可能涉及到滤波、屏蔽或接地等措施,以减少信号泄漏和电流波动。 - **解决之道**:给出了具体的整改措施,包括可能的硬件改进、电路设计优化或软件算法调整,以降低辐射、静电和浪涌的影响。 - **一试究竟**:这部分详细描述了实施整改方案的过程,包括实际操作步骤、效果验证以及必要的测试,以确保整改方案的有效性和合规性。 总结来说,AN-0 Coconut EMC整改案例是一份实用的技术文档,展示了如何针对特定产品在电磁兼容性测试中遇到的问题进行分析和解决,旨在提升产品的电磁兼容性,符合相关法规要求,确保在实际应用中的稳定性和安全性。

解决这个问题King Julien rules the Madagascar island whose primary crop is coconuts. If the price of coconuts is P , then King Julien’s subjects will demand D(P ) = 1200 − 100P coconuts per week for their own use. The number of coconuts that will be supplied per week by the island’s coconut growers is S(p) = 100P. (a) (2 pts) Calculate the equilibrium price and quantity for coconuts. (b) (2 pts) One day, King Julien decided to tax his subjects in order to collect coconuts for the Royal Larder. The king required that every subject who consumed a coconut would have to pay a coconut to the king as a tax. Thus, if a subject wanted 5 coconuts for himself, he would have to purchase 10 coconuts and give 5 to the king. When the price that is received by the sellers is pS, how much does it cost one of the king’s subjects to get an extra coconut for himself? (c) (3 pts) When the price paid to suppliers is pS, how many coconuts will the king’s subjects demand for their own consumption (as a function of pS)? 2 (d) (2 pts) Under the above coconut tax policy, determine the total number of coconuts demanded per week by King Julien and his subjects as a function of pS. (e) (3 pts) Calculate the equilibrium value of pS, the equilibrium total number of coconuts produced, and the equilibrium total number of coconuts consumed by Julien’s subjects. (f) (5 pts) King Julien’s subjects resented paying the extra coconuts to the king, and whispers of revolution spread through the palace. Worried by the hostile atmosphere, the king changed the coconut tax. Now, the shopkeepers who sold the coconuts would be responsible for paying the tax. For every coconut sold to a consumer, the shopkeeper would have to pay one coconut to the king. For this new policy, calculate the number of coconuts being sold to the consumers, the value per coconuts that the shopkeepers got after paying their tax to the king, and the price payed by the consumers.
