"单片机精编版实现HZ正弦交流信号有效值测量"。

In the document "HZ正弦交流信有效值的测量单片机精编版.pdf", the measurement of the effective value of AC sine waves using a single-chip microcontroller is discussed. The effective value is a widely used parameter in practical applications, as it directly reflects the energy of the AC signal. This is important for studying power, noise, distortion, spectral purity, energy conversion, and other aspects. The simplicity and convenience of calculating effective values make them a popular choice for measurement. The design of this course uses the STC89C51 single-chip microcontroller as the control core, utilizing the AD736 chip for measuring the effective value of sine waves. The measurement results are amplified and then converted by the TLC549 chip for display on an LCD screen under the control of the microcontroller. Keywords: effective value, AD736, TLC549 Overall, the document details a practical and efficient method for measuring the effective value of AC sine waves using a single-chip microcontroller. By utilizing specialized chips and careful design, accurate measurements can be obtained and displayed for a variety of applications.
