ABSTRACT:
In a synchronizing circuit receiving a bit stream including a synchronous pattern and various kinds of information bits, for outputting a synchronous signal, there is provided a synchronous pattern register which is previously set with known information bits of the layer, the bit rate and the sampling frequency. A synchronous pattern detecting circuit is configured not to recognize as a synchronous pattern, a synchronous pattern having the values other than previously set values. With this arrangement, it is possible to remarkably reduce probability that a quasi synchronous pattern is detected as the synchronous pattern, and therefore, it is possible to minimize missing of sound corresponding to the digital audio signal.
