Title: Receiving circuit and portable telephone using the same
Inventor: ARAGAI YUJI
IPC: H04B1/40
Filed: 2001-04-26
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration in the sound quality of a loudspeaker 70. SOLUTION: When the power value of a receiving PCM signal is >= a prescribed threshold, a microcomputer 140 controls a power amplifier 40 so that a gain can become '1'. Therefore, the power value of a power amplifying signal becomes equal to the power value of the receiving PCM signal. When it is decided that the power value of the receiving PCM signal is less than the prescribed threshold, the microcomputer 140 controls the power amplifier 40 so that the power value of the power amplifying signal can be fixed by a greater variable gain in comparison with '1'. Therefore, the power value of the power amplifying signal is larger than the power value of the receiving PCM signal and the power value of the power amplifying signal is fixed.  Since the loudspeaker 70 outputs sounds on the basis of such a power amplifying signal, the volume of the loudspeaker 70 can be prevented from exceeding the maximum output range of the loudspeaker 70.
