标题中的"IIR低通数字滤波器C语言有图"是指使用C语言实现了一种无限 impulse response (IIR) 低通数字滤波器，并且提供了相关的图形展示。这种滤波器在信号处理领域有着广泛的应用，常用于去除噪声、平滑数据或选择性地保留特定频率成分。 IIR低通数字滤波器是一种滤波算法，其工作原理基于过去的输入和输出值的线性组合，形成了一个无限的响应。相比于有限 impulse response (FIR) 滤波器，IIR滤波器通常需要更少的计算资源，但可能会引入一些非线性失真。 C语言是编写这种滤波器的常用编程语言，因为它的效率高，且适合处理实时的信号处理任务。描述中提到的"Easy-x插件画图"可能是指利用EasyX图形库，它是一个为Windows平台设计的C/C++图形库，可以帮助开发者快速绘制出滤波器的输入输出波形，便于理解和调试。在设计IIR滤波器时，通常会涉及以下步骤： 1. **滤波器规格确定**：根据应用需求，设定截止频率、阻尼比和通带/阻带衰减等参数。 2. **滤波器设计**：可以使用巴特沃斯、切比雪夫I型、切比雪夫II型或椭圆函数等设计方法，来获得理想的频率响应。 3. **系数计算**：基于所选的设计方法，计算IIR滤波器的系数，如直接形式I、直接形式II、二阶节形式等。 4. **滤波器实现**：将计算出的系数应用于C语言代码中，实现滤波器的结构，如递归累加等形式。 5. **错误检查与调试**：描述中提到的“程序有一个错误，生成原始波形的储存位置应该改成E盘”，这涉及到程序的路径设置问题，需要在代码中修正，确保数据能够正确保存和读取。在压缩包内的"ConsoleApplication1"可能是包含了整个项目的源代码，包括滤波器的实现以及使用EasyX库进行图形绘制的部分。为了进一步理解这个项目，需要查看源代码，分析滤波器的实现细节，以及如何使用EasyX进行图形化显示。总结起来，这个项目提供了一个使用C语言实现的IIR低通数字滤波器实例，通过图形化展示帮助用户理解滤波器的效果。对于学习信号处理和C语言编程的人员来说，这是一个很好的实践案例，可以帮助他们了解滤波器设计和编程实现的关键步骤。
