摘要： An analog-to-digital conversion device and a method thereof are provided. The analog-to-digital conversion device includes a first level adjustment unit, an analog-to-digital converter (ADC), and a linear range detection unit. The ADC converts a test signal or a first input signal to generate a test data stream or a first output data stream. In an adjustment mode, the linear range detection unit obtains a conversion curve of the ADC by using the test data stream and determines whether to adjust offset control information according to a linear range of the conversion curve. In an operation mode, the linear range detection unit continues outputting the offset control information. Additionally, before transmitting the first input signal, the first level adjustment unit adjusts a direct-current level of the first input signal according to the offset control information to allow the first input signal to be within the linear range of the conversion curve.

摘要： A data recovery device including a filter, a tilt detection unit, a tilt cancellation unit and a data conversion unit is provided. The filter filters a radio-frequency data stream to generate an original data stream. The tilt detection unit synthesizes a tangential push-pull data stream by employing a first to a fourth data streams, and generates a tilt direction signal according to symmetry of a curve composed by the tangential push-pull data stream. The tilt cancellation unit detects a plurality of rising areas and falling areas of the original data stream, and reconstructs a plurality of data points corresponding to the rising areas or falling areas in the original data stream so as to generate a tilt repair data stream. The data conversion unit recovers the tilt repair data stream to a modulation signal.

摘要： A data recovery method includes the following steps. Firstly, plural sampling values are classified into a first group, a second group, a third group and a fourth group. A first channel estimation value and a second channel estimation value are generated according to the sampling values of the second group and the third group. A judging step is performed to judge whether a first sampling value of the first group is lower than the first channel estimation value or a second sampling value of the fourth group is higher than the second channel estimation value. If the judging condition is satisfied, a polarity of the first sampling value or the second sampling value is changed and then the plural sampling values are outputted. If the judging condition is not satisfied, the plural sampling values are directly outputted.
