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.

為減少測(cè)試數(shù)據(jù)存儲(chǔ)量,提出一種有效的新型測(cè)試數(shù)據(jù)壓縮編碼———PTIDR 編碼,并構(gòu)建了基于該編碼的 壓縮P解壓縮方案1 PTIDR 編碼能夠取得比FDR ,EFDR , Alternating FDR 等編碼更高的壓縮率,其解碼器也較簡(jiǎn)單、 易實(shí)現(xiàn),且能有效地降低硬件開(kāi)銷(xiāo)1 與Selective Huffman , CDCR 編碼相比,PTIDR 編碼能夠得到較高的壓縮率面積 開(kāi)銷(xiāo)比1 特別地,在差分測(cè)試集中0 的概率滿足p ≥017610 時(shí),PTIDR 編碼能取得比FDR 編碼更高的壓縮率,從而 降低芯片測(cè)試成本1
