<p>After a pseudo synchronizing information is detected and a synchronization is lost, an arithmetic operation unit adds a random number outputted from a random number generator to a frame length information calculated. The detection of a synchronizing information is again executed in a stream counter to a bit stream of a plurality of continuous transmission data, from a bit located in delay for the bit of output information being a calculation result by the arithmetic operation unit. The frame synchronous circuit thus constructed achieves a synchronization setup securely in a high speed, if a transmission data containing a pseudo synchronizing information is transmitted.</p> |
