A measure system for signal measurement is introduced. The measure system simplifies the effort for a signal measurement in many applications. The application for a signal measurement is, for example, computation of a signal average value. The measure system includes a digital computation circuit together with an analog to digital converter (ADC) to constitute a compact signal measurement component. With the proposed design, a general microcontroller can proceed with a signal level sense and control with very few CPU power. In addition, the proposed system can be integrated with other analog or digital signal processing circuitry to form a single silicon chip.
