Abstract: PROBLEM TO BE SOLVED: To provide a computer system including a modem card improved in the sound quality of an audio signal. SOLUTION: An audio signal is sometimes provided a mute circuit (514, etc.), is provided for an audio signal for preventing noise applied on the audio signal from a modem. It is possible to construct a mute circuit for improving the sound quality of such an audio signal without needing large design change to a modem subsystem (260) and also in an inexpensive method by concretely using, e.g. an off-hook (OFF-HOOK) signal (512) that already exists in the modem subsystem as a gate (G) input.

Abstract: PROBLEM TO BE SOLVED: To improve an S/N ratio in a mute state by informing an information processor of the fact that it is in the mute state when the read out data are not the audio data. SOLUTION: A CPU: 220 discriminates whether a signal read by an optical head 211 is either of the audio data or the computer data. When the read data are the audio data, the data are sent out through a DAC: 230, and the CPU: 220 informs the information processor of the mute signal of a low level. Further, when the read data are the computer data, the data are sent out to the information processor through a decoder circuit 240A and an interface circuit 240B, and the CPU: 220 outputs the mute signal of a high level to the information processor. High potential is applied to the gate of an FET switch 270, and an output of a driver 232 is lowered to a grounded level, and the occurrence of a noise is prevented.

Abstract: PROBLEM TO BE SOLVED: To provide an excellent information processor in which the power saving operation of a sound function can be executed according to the activity of each peripheral equipment having an audio signal output. SOLUTION: It is judged whether or not each peripheral equipment for outputting an audio signal is in a mute state, and a mixer circuit 37A is energy dissipated only for a period when all the peripheral equipment are in a mute state. Also, the mute state of each peripheral equipment and a 'power control flag' in the I/O register of an audio controller 37 are monitored, and even when the power control flag is erroneously set by software during the input of the audio signal from any peripheral equipment, or even when performance is started by the operation of an equipment also used for an audio function such as a CD-ROM drive side during the setting of the power control flag, the mixer circuit 37A can be surely re-enabled.

Abstract: PROBLEM TO BE SOLVED: To provide a control method for a wireless LAN module for efficiently exchanging data. SOLUTION: First of all, it is decided whether or not a power source for supplying power is an AC adapter (step S201). When the power source is the AC adapter, data are exchanged (step S206). When the power source is not the AC adapter, on the other hand, the state of a link with an access point is measured (step S202) and further, when a radio wave strength is lower than a threshold as a result of measurement, a channel search is carried out (step S204) so that data are transmitted/received to a new access point (steps S205 and S206). In such a control method, when the power source is the AC adapter, data can be continuously exchanged without measuring the link state or carrying out the channel search.
