摘要: A method is provided for measuring a resistance value of resistive component, which provides connecting pull up resistance, in series to the component and supplying first voltage free end second lower monitoring signal indicative between determining difference monitored generated PWM having high low value, integrating difference, obtaining an output signal, varying duty cycle based on variation over time acquiring value.
