<P>PROBLEM TO BE SOLVED: To provide a signal processor which saves on power by a simple control. <P>SOLUTION: The signal processor is equipped with: a first signal generation part which generates a first data signal synchronized with a first clock having a frequency f1 from first data; a second signal generation part which generates a second data signal synchronized with a second clock having a frequency f2=N*f1 and in which a value obtained by totaling amplitude for a 1/2 period of the first clock becomes zero from second data; a signal addition part which adds the first data signal generated by the first signal generation part and the second data signal generated by the second signal generation part together to generate an addition signal; a signal transmission part which transmits the addition signal generated by the signal addition part; and a control circuit which always operates the first signal generation part, operates the second signal generation part when the second data is transmitted, and stops an operation of the second signal generation part when the second data is not transmitted. <P>COPYRIGHT: (C)2011,JPO&INPIT |
