Signal processing device, signal processing method, and program

A signal processing method comprising the steps of:

• determining an influence of a digital data processing circuit on an analog signal processing circuit;
• controlling to stop a partial circuit of the digital data processing circuit or lower processing capability thereof in response to a determination result of the determining step;
• and
• operating the analog signal processing circuit and the digital data processing circuit in a state in which the partial circuit has been stopped or the processing capability thereof has been lowered.

A program causing a computer to execute:

• determining an influence of a digital data processing circuit on an analog signal processing circuit;
• controlling to stop a partial circuit of the digital data processing circuit or lower processing capability thereof in response to a determination result of the determining process;
• and
• operating the analog signal processing circuit and the digital data processing circuit in a state in which the partial circuit has been stopped or the processing capability thereof has been lowered.

A signal processing device comprising:

• an analog signal processing circuit;
• a digital data processing circuit;
• a determination section configured to determine an influence of the digital data processing circuit on the analog signal processing circuit;
• and
• a control section configured to raise noise cancelling capability of the analog signal processing circuit or the digital data processing circuit in response to a determination result of the determination section.
