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 ...

You probably have needed to match impedances and levels from time to time. Perhaps you want to connect a consumer computer’s sound card to your console; or you need to lower a balanced output level to ...

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 ...
