Abstract
PURPOSE:To improve error detecting accuracy by sectioning an information bit into plural sections at a transmitting side, counting the number of '1's or '0's included in the section and forming a frame for the counted result together with counted bits. CONSTITUTION:The information bit is inputted from a signal input terminal 1 and the number of '1's is counted in each (n) bit by a counting circuit 2. For the counted result, the frame is formed by a frame generating circuit 3 together with the information bit and sent to a transmitting path 4. In a receiving side, the counting circuit 5 counts the number of '1' of the information bit in a receiving frame and a counted result detecting circuit 6 detects a counted result bit in the receiving frame. The output results of the counting circuit 5 and the counted result detecting circuit 6 are compared by a code error detecting circuit 7 and when there is dissidence, an error generating signal is outputted to an output terminal 8.
