When soldered to a 2V-input, 31⁄2 digit DMS-30 Series meter, the DMS-EB-RMS Application Board enables the meter to display the true rms value of AC voltages up to 750V with a resolution of 1V. When ...

On infrequent occasions, I am asked to design a circuit to measure the RMS value of a current or voltage for some kind of power measurement. Since the work I do is hardly unique, I thought some of you ...

The variety of test and measurement products available today can boggle the mind. From the mundane to the exotic, these instruments can practically lead you by the hand. However, if you don't have a ...

The design of a true 100µV rms-to-DC converter can be straight-forward, explain Chau Tran and David Karpaty from Analog Devices. A fundamental measure of an ac signal, root mean square (rms) is ...
