Analog Circuit Analysis can be difficult. Consider the circuit below. It includes a Series Resonant Circuit. With Ideal Impedances, the Series Impedance is equal to zero at the resonant frequency. A ...

The basic concepts underpinning time-domain reflectometry. Difference between frequency- and time-domain analysis. Some applications of TDR measurements. Time-domain reflectometry (TDR) is a technique ...

Measuring the output impedance of wideband op amps presents a formidable challenge because of their high DC gain, which results in low closed-loop output impedance at low frequencies. Above the ...

Electrical impedance myography (EIM) is a non‐invasive technique that employs a weak, high‐frequency electrical current to assess the electrical properties of muscle tissue. By measuring resistance, ...

If you catch a grizzled old radio amateur propping up the bar in the small hours, you will probably receive the gravelly-voiced Wisdom of the Ancients on impedance matching, antenna tuners, and LC ...

All transformers have nameplates, and all manufacturers use the same nomenclature for capacity, ratings, impedance, and other pertinent information. This article focuses on dry- or oil-type ...

A common joke in electronics is that every piece of wire and PCB trace is an antenna, with the only difference being whether this was intentional or not. In practical terms, low-frequency wiring is ...
