    • An apparatus and a method for gain adjustment for analog YPbPr signals are provided. The apparatus comprises a first clamping circuit, an analog-to-digital converter (ADC), and a gain calculator. The first clamping circuit clamps the lowest potential of a horizontal synchronization signal of a Y signal of an analog YPbPr signal to 0 V. The ADC converts the clamped Y signal from an analog signal to a digital signal and then outputs the digital signal. The gain calculator receives the actual peak-to-peak voltage of the horizontal synchronization signal from the ADC, and then calculates and sets the gain for the ADC according to the peak-to-peak voltage.
    • 提供了一种用于模拟YPbPr信号的增益调整的装置和方法。 该装置包括第一钳位电路,模数转换器(ADC)和增益计算器。 第一个钳位电路将模拟YPbPr信号的Y信号的水平同步信号的最低电位钳位到0V。ADC将钳位的Y信号从模拟信号转换为数字信号,然后输出数字信号。 增益计算器从ADC接收水平同步信号的实际峰 - 峰电压,然后根据峰峰值电压计算并设置ADC的增益。
