Engineers usually have access to signal and function generators, as well as frequency counters and oscilloscopes, but they may not have access to capacitance or inductance meters. Using the test setup ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

Although it dates back to the early days of the Marconi Company in the 1920s, the Franklin oscillator has remained a ...

The components in a home audio/video system are pretty complicated to anyone without a good understanding of electronics; but wire–good, old-fashioned wire–is something we can all understand. It’s ...

Appropriately cut quartz crystals can be used as high-quality electromechanical resonators. Their piezoelectric properties (voltage across the crystal deforms it; deforming the crystal generates a ...

The WAMT and MSMW series of 40-GHz resistor terminators from Mini-Systems Inc. offer very low parasitic capacitance and inductance. They come in 0.020- by 0.010-in. packages with values from 3 to 400 ...
