PROBLEM TO BE SOLVED: To suppress a band variation of a signal processing device that is dependent upon a digital signal code.SOLUTION: In a signal processing device 100, a digital-to-analog converter (DAC) 101 converts a digital signal to an analog signal. A band limiting filter 102 limits a band of an analog signal. A filter circuit 103 controls a band of the band limiting filter 102 in accordance with a level of a digital signal.SELECTED DRAWING: Figure 1 |
