Multiplexed signal demultiplexing device transmission error measuring device and transmission error measuring method

摘要

The transmission error measuring device comprises; a first counting circuit, a test data outputting circuit, a selecting circuit, a multiplexing circuit, a demultiplexing circuit, an arranging circuit, a data array monitoring circuit, a second counting circuit, a reference data outputting circuit, and a comparing circuit. When a test data outputted from the test data outputting circuit does not correspond to a reference data outputted from the reference data outputting circuit, the data array monitoring circuit rearranges the first count value by using a bit set at the bottom thereof in order to rearrange the test data.
