摘要： Disclosed are a method and device of converting data words into code words. This method inserts 2p p guided bits before inputting each set of data words, performs a pre-defined operation, and generates 2p data sequences with different guided bits. It chooses q data sequences from the 2p data sequences for coding, performs a run length limited (RLL) coding with a coding rate m/n, and generates q (d, k) constrained code word sequences. Finally, an optimal (d, k) constrained code word sequence is selected from the q (d, k) constrained code word sequences. The device reduces the circuitry of the RLL coding applied guided scrambling without losing the control of direct current and low frequency components.

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.
