产生一些常见的离散时间信号完成两个有限长序列的线性卷积和,用滑动平均滤波器对混有噪声的信号进行滤波(Some common discrete time signals are generated to complete the linear convolution sum of two finite sequences, and the mixed noise signals are filtered by moving average filter.)

Android实现五种不同外观样式的Toast弹出框效果，演示了自定义位置的Toast显示、带图片的Toast显示、完全自定义的Toast显示、长时间的Toast显示5种Toast，在效果测试时，你可以单击任意一种Toast，查看对应的弹出提示效果是什么样子，这些Toast在android应用开发时，用的比较多。
