Claim Text:
1. A signal processing device, comprising: a sampling module configured to sample an input signal to generate a sample signal; a first segmentation module configured to calculate a first segment value according to the sample signal during a first time interval, wherein the first segmentation module calculates sample data of the sample signal within the first time interval to derive the first segment value; a second segmentation module configured to calculate a second segment value according to the sample signal during a second time interval, wherein the second segmentation module calculates sample data of the sample signal within the second time interval to derive the second segment value, and the length of the first time interval is different from that of the second time interval; and a detection module, coupled to the first segmentation module and the second segmentation module, configured to generate a detection signal according to the determination of whether the first segment value lies out of a first range, and whether the second segment value lies out of a second range.
