this is a digital intercom projects using ADC PWM and UART interrupt. you take the value from mic enter it to ADC and then send serially to the other microcontroller which receives the data and transform the digital data into analog data by PWM which is connected to speaker

A Convex Hull is the smallest convex polygon that contains every point of the set S. A polygon P is convex if and only if, for any two points A and B inside the polygon, the line segment AB is inside P. One way to visualize a convex hull is to put a "rubber band" around all the points, and let it wrap as tight as it can. The resultant polygon is a convex hull.

为减少测试数据存储量,提出一种有效的新型测试数据压缩编码———PTIDR 编码,并构建了基于该编码的 压缩P解压缩方案1 PTIDR 编码能够取得比FDR ,EFDR , Alternating FDR 等编码更高的压缩率,其解码器也较简单、 易实现,且能有效地降低硬件开销1 与Selective Huffman , CDCR 编码相比,PTIDR 编码能够得到较高的压缩率面积 开销比1 特别地,在差分测试集中0 的概率满足p ≥017610 时,PTIDR 编码能取得比FDR 编码更高的压缩率,从而 降低芯片测试成本1
