Electrical Noise in Motion Control Circuits
. Electrical Noise in Motion Control Circuits. 1. Origins of Electrical Noise. Electrical noise appears in an electrical circuit through one of four routes: a. Impedance (Ground Loop) Coupling. b. Capacitive (Electrostatic) Coupling. c. Inductive (Magnetic) Coupling. d. Electromagnetic (Radio Frequency

An Overview of Electromagnetic and Lightning Induced Voltage Transients (.pdf)
This Note is an overview of the sources and nature of various transient overvoltages, and the problems that may result. Transients in electrical circuits result from the sudden release of previously stored energy. This energy can be stored within the circuit and released by a voluntary

Understanding Ring Generators
, the only difference is the AC outlet provides 110 to 220VAC at 60Hz or 50Hz. The ring generator typically provides 45 to 90VAC at different frequencies. The low frequency is needed for electromechanical bell telephones. Old telephone sets equipped with these mechanical bells use a large inductor

What is an Electrical Transient?
p>An electrical transient is a temporary excess of voltage and/or current in an electrical circuit which has been disturbed. Transients are short duration events, typically lasting from a few thousandths of a second (milliseconds) to billionths of a second (nanoseconds), and they are found on all

Krytar Directional Couplers: Term Definitions, Testing, and Typical Applications (.pdf)
. Couplers usually have two separate circuits. The first. is a mainline circuit and the second is a coupled circuit. When microwave power is applied to the mainline. circuit (Ports 1 and 2) a certain amount of energy will be "coupled" to the coupled circuit (port 3). In general,. the closer the circuits
