Method and apparatus for measuring the mean square value of an electrical signal |
摘要 |
A method and apparatus for measuring the RMS value of an electrical signal. An electrical signal is converted to a digital signal. The digital signal is squared and low pass filtered to extract the DC component, the DC component being recognized as the mean-square of the signal. In use in a measurement device, the square root of the DC component is taken and displayed as the RMS value of the electrical signal.
