Using a voltmeter, we would like to measure the voltage V = V1-V2 as shown in the circuit above. What is the value of V? What is the common-mode voltage Vcm associated with V? What CMRR (in dB) is ...

It's no longer sufficient to just perform static CMR tests on isolators. You have to look at the dynamic performance of optical, magnetic, capacitive, and RF implementations. Static common-mode ...

Since the dawn of time—or at least since the dawn of precision electronics—a major headache for analog designers has been CMV (common-mode-voltage)-induced errors, also known as the dreaded ground ...

According to IEEE/ANSI Standard C62.41-1991 (formerly IEEE Standard 587), Recommended Practice on Surge Voltages in Low-Voltage AC Power Circuits, the worst normal mode surge expected inside a ...

Common-mode rejection is the ability of the differential amplifier (which sits between the oscilloscope and probes as a signal-conditioning preamp) to eliminate the common-mode voltage from the output ...

In discussing the characteristics and performance of various interconnect systems; two points should be kept in mind. Balance is defined in terms of the impedance of the two signal conductors with ...
