摘要： In a signal processing apparatus, a high frequency level detecting unit detects a level of a high frequency component adjusted with a first adjusting unit, and a first control unit controls a first gain of the adjusting unit according to the level of the high frequency component thus detected. Further, a low frequency level detecting unit detects a level of a low frequency component adjusted with a second adjusting unit. A second control unit controls a second gain according to the level of the high frequency component and the level of the low frequency component thus adjusted, so that a difference between the level of the high frequency component adjusted with the first adjusting unit and the level of the low frequency component adjusted with the second adjusting unit becomes smaller than a specific level determined in advance.

摘要： This method is applied to a dual-use jack of an electronic device. Either a headphone plug or a line output plug is inserted into the dual-use jack. The method determines the type of a plug connected to the dual-use jack when the plug is inserted into the dual-use jack. The determination is made based on a load resistance of the plug connected to the jack. The method includes feeding an electric current through the load resistance in a first direction. The method compares a voltage across the load resistance to a reference voltage and determines the type of the plug in use. The method also includes feeding an electric current through the load resistance in a second direction. This electric current can reduce or eliminate a pop-noise when the plug type is determined. The second direction is different from the first direction.

摘要： A signal processing device includes a non-inverting amplifier, an inverting amplifier, a converter, and a controller. The non-inverting amplifier amplifies a level of an analog sound signal input from outside with a first gain whose value is variable. The inverting amplifier amplifies a level of the analog sound signal amplified by the non-inverting amplifier with a second gain whose value is variable. The converter converts the analog sound signal amplified by the inverting amplifier to a digital sound signal. The controller detects a level of the digital sound signal converted by the converter and, in accordance with the detected level of the digital sound signal converted by the converter, controls the first gain and the second gain such that a level of the analog sound signal input to the converter is at a pre-specified level.
