Abstract: A circuit for amplifying and outputting a pulse width modulated (PWM) signal corresponding to an input audio signal with at least one output transistor and at least one protection control circuit. The protection control circuit compares a detected voltage and a threshold voltage. The detection voltage is a potential difference between a source and a drain of the output transistor. When the detection voltage exceeds the threshold voltage, the protection control circuit outputs a short circuit detection signal to the gate of the output transistor. As a result, the output transistor is turned OFF.

The protection control circuit compares a detection voltage and a predetermined voltage. The detection voltage is a potential difference between a source and a drain of the output transistor. When the detection voltage exceeded the predetermined voltage, the protection control circuit outputs a short circuit detection signal to the gate of the output transistor. As a result, the output transistor is turned OFF.

Abstract: When a signal indicating a transition state from a synchronized state to an asynchronous state is outputted from a synchronous state register 8, data "0" generated by a "0" generating circuit 20 are stored in a data memory 10 instead of an output of an audio signal generating circuit 6, thus initializing the data memory 10 in advance. In a conventional coded-signal decoding circuit, when a transition was made from a synchronized state to an asynchronous state after failing to establish synchronization, the data memory 10 had to be initialized at a point in time before starting the next synchronous detection, presenting a problem in terms of time. To achieve this, a synchronous control method, a synchronous detecting circuit, and a synchronous detection method are provided.
