Test and Measurement World

“Bill & Dave” takes you through not only the history of the Hewlett-Packard Company, it gives you insight into how the company’s founders thought and acted. Malone particularly points to how Hewlett and Packard dealt with people. He cites many “war” stories, starting at Stanford, through World War II, when Hewlett left the fledgling company for Packard to run, and onward through Packard’s death in 1996 and Hewlett’s death in 2001.”

“RMS to DC conversion is the truest way to measure the energy contained in an AC waveform.” The accurate measurement of AC for a wide variety of waveforms and noise is difficult. When we make solar systems and inverters, the AC outputs are seldom sinusoidal. The easy method is to use a Precision rectifier/filter, get the average voltage and a RMS calibration/scaling is done for sine is by tweaking a trimpot. This will not show the right values for other waveforms. The other way was, analog computing, with many opamps and a matched pair of transistors; like multipliers and log [Read More ....]
