RUN LENGTH CODING CIRCUIT

摘要

PURPOSE:To obtain a stable output signal by switching and outputting a run length code outputted by a first coding means and a transformed code outputted by a second coding means for a prescribed synchronizing unit. CONSTITUTION:The first coding means 100 transforms input data which is not delayed to the run length code in an initial cycle in which the input data is changed from a predetermined value to other value. The second coding means 200 transforms the input data incoming in a cycle after the predetermined value is changed to other value with a delay by one cycle by a delay means 400. A switching means 300 switches the run length code outputted by the first coding means 100 and the transformed code outputted by the second coding means 200 with the prescribed cycle unit to output them.
