Last month, we showed how you could use vector diagrams and simple math to calculate neutral currents in 3-phase, 4-wire circuits. In this last installment, we'll talk about using simple parallelogram ...

AES3 digital signals are being used more and more everyday. There are two versions of this standard. One is a balanced signal passed over a twisted-pair wire with a characteristic impedance of 110 ...

LONDON. Physical Society, October 27.—Prof. J. H. Poynting, F.R.S., president, in the chair.—The theory of phase-meters: Dr. W. E. Sumpner. The author shows in the paper that the theory of the ...

A phase vector or phasor in physics and engineering signifies a sine wave whose amplitude and frequency are time-variant. The behavior of a sinusoid is decomposed by phasors into three independent ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
