Abstract
A method for correcting an analog signal to target levels is provided. Firstly, the analog signal is periodically sampled to obtain a plurality of sampled points. Then, levels of the sampled points are compared with a threshold value to find a set of sequentially sampled points including a head and a tail ones, each having a first comparing result with the threshold value, and the other intermediate ones, each having a second comparing result with the threshold value. Then, one of the set of sequentially sampled points, which has the second comparing result with the threshold value, is adjusted to one of the target levels. A device for correcting an analog signal to target levels is also provided.
