摘要：An analog signal measuring device for measuring an analog signal includes adigital controller, a waveform converter and a comparator. The digital controller includesa PWM controller for outputting a pulse signal having an adjustable pulse width to thewaveform converter, which converts the pulse signal into a sawtooth wave or a triangle

wave for output as a carrier signal. Next, the comparator feeds a comparison pulse signal,which is obtained by comparing the carrier signal to the analog signal, to the digitalcontroller, which enables or disables the counter to generate a count value

corresponding to the comparison pulse signal. Since the count value depends on thecomparison pulse signal and the type of the comparison pulse signal is directly related tothe analog signal, the digital controller may get the analog signal according to the countvalue.
