<p>PURPOSE:To attain the transmission of a frame signal with a simple circuit by sending clock signal serving as a frame information and clock information on a transmitting side, receiving the clock signal on a receiving side, and separating the frame information from the clock information. CONSTITUTION:The clock signal, which is level-controlled beforehand and inputted from an input terminal 2, is bifurcated. The clock signal is decided that it has no pulse by a level decider 11, the output is inputted to a retriggerable one-shot multi-vibrator 13, the straggled pulse appears as a '0' level, is inputted to a logical inversion circuit 14, and is made into the pulse of a '1' level, on the contrary, the clock decided by a level decider 12 is reproduced as a normal unstraggled clock. The pulse is inputted to an AND circuit 15, the pulse coincident with the time position of the frame signal is obtained when the AND is removed, and the pulse is used as the frame information in a multiple or separating circuit 16. Thus, the frame signal can be easily transmitted with the simple circuit.</p> |
