Abstract
A voltage sampling system is provided. The voltage sampling system includes a first and a second input paths and a signal-processing module. The first input path includes a first input voltage-dividing resistor unit, a second input voltage-dividing resistor unit and a first DC voltage-dividing resistor unit to generate a first input divided voltage and a first DC bias voltage to further generate a first sampled voltage signal according to a first input voltage and a DC voltage source. The second input path includes a third input voltage-dividing resistor unit, a fourth input voltage-dividing resistor unit and a second DC voltage-dividing resistor unit to generate a second input divided voltage and a second DC bias voltage to further generate a second sampled voltage signal according to a second input voltage and the DC voltage source. The signal-processing module receives the first and the second sampled voltage signals to perform signal processing.
