PURPOSE:To limit a pulse width distortion of a decoded auxiliary signal within one bit of a main signal by converting information representing a change in the auxiliary signal into violation occurrence interval and sending the result. CONSTITUTION:A main signal input (a) inputted to a transmission section 1 is converted into a CMI code string by a CMI code conversion circuit 3. On the other hand, the leading of an auxiliary signal input (b) inputted to the transmission section 1 is detected by a leading detection circuit 4 and the trailing is detected by a trailing detection circuit 5. All n-bit, violation designation circuit 6 designates violation of n-bit interval with an auxiliary signal leading detection signal (e) of the circuit 4 and an m-bit violation designation circuit 7 designates the violation of m-bit of interval by using all auxiliary signal trailing detection signal (d) from the circuit 5 to form a violation designation pulse (e). The pulse (e) is inputted to the circuit 3 and violation is applied to the CMI code string of the main signal for the time slot of the pulse (e). Thus, a signal (f) subjected to violation corresponding to the change point of the input (b) is sent to the reception section 2. |
