Standing Waves on Transmission Lines and VSWR Measurements

Foundations Consider the transmission line circuit shown in Figure 1. A sinusoidal voltage source with its source impedance drives a lossless transmission line with characteristic impedance ZC, terminated in... Read More...

Conducted Emissions Measurements: Current Method

This article is devoted to the current method of the conducted emissions measurements.

Current Probe Measurements in EMC Testing

This article focuses on the current probes used in EMC measurements and testing.

Conducted Emissions Measurements: Voltage Method

This article describes the voltage method of the conducted emissions measurements.

Human-Body Model and Electrostatic Discharge (ESD) Tests

Consider a spherical capacitor consisting of two concentric, conducive spheres separated by a dielectric.

Spectra of Digital Clock Signals

Reducing the duty cycle (the pulsewidth) reduces the low-frequency spectral content of the waveform, but does not affect the high-frequency content.

Transmission Line Reflections at a Discontinuity

In this article, we consider the effects of a discontinuity along the transmission line which occurs when the transmission line characteristic impedance changes.

Transmission Line Reflections at a Resistive Load

Consider a transmission line of length driven by a constant voltage source with a source resistance, and terminated by a resistive load.
