In binary digital transmission, a bit error rate (BER) is the most important evaluation standard. But actual transmission line does not give any bit error rate, because a bit error occurs by existence of analog noise power. If these noisy communication channel which shows a certain random bit error rate, called a transmission line simulator, can be constructed artificially, it is very useful for evaluation of data transmission quality. This paper proposes the theoretical design method of transmission line simulator using a combination of the maximum length sequence generator and binary counter circuits or two maximum length sequence generators. Changing the length of shift register, average bit error rate is controlled. The fundamental concept and its characteristics are described.
