### Smith Chart and Input Impedance to Transmission Line, Part 3: Input Impedance to the Line

This article explains how to use a Smith Chart to determine the input impedance to transmission line at a given distance from the source or the load.

### Smith Chart and Input Impedance to Transmission Line

This is the second of the three articles devoted to the topic of a Smith Chart.

### Smith Chart and Input Impedance to Transmission Line, Part 1: Basic Concepts

This is the first of the three articles devoted to the Smith Chart and the calculations of the input impedance to a lossless transmission line.

### Basic EMC Rules

This article discusses the origins, justification, and interrelations between some of basic EMC rules regarding the highest significant frequency (bandwidth) present in digital signals, definition of the electrically short structures, and the transmission line criterion.

### Circuit Theory Model of Ringing on a Transmission Line

This article uses a classical circuit-theory model of a series RLC circuit to explain the phenomenon of ringing on a transmission line, or a PCB trace.

### Transmission Line Reflections: Bounce Diagram

This article explains the creation of a bounce diagram for a transmission line circuit (see [1] for transmission line reflections).

### Transmission Line Pulse Testing: The Indispensable Tool for ESD Characterization of Devices, Circuits and Systems

Transmission Line Pulse testing is the default method for characterizing the behavior of devices under ESD circumstances.

### 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.
