  1. Impulse generator

    Unreferenced date November 2010 An Impulse generator is an electrical apparatus which produces very short high voltage or high current surges. Such devices can be classified into two types impulse voltage generators and impulse current generators. High impulse voltages are used to test the strength of electric power equipment against lightning and switching surges. Also, steep front impulse voltages are sometimes used in nuclear physics experiments. High impulse currents are needed not only for tests on equipment such as lightning arresters and fuses but also for many other technical applications such as lasers, thermonuclear fusion, and plasma devices. Marx generator One form is the Marx generator , after E. Marx who first proposed it in 1923. This consists of multiple capacitors that are first charged in parallel through charging resistors by a high voltage, direct current source and then connected in series and discharged through a test object by a simultaneous spark over of the spark gaps. The impulse current generator comprises many capacitors that are also charged in parallel by a high voltage, low current, direct current source, but it is discharged in parallel through resistances, inductances, and a test object by a spark gap.

When a force is applied to a rigid body it changes the momentum of that body. A small force applied for a long time can produce the same momentum change as a large force applied briefly, because it is the Product mathematics product of the force and the time for which it is applied that is important.

The bilinear transform is an alternative to impulse ... time case, as opposed to mapping frequencies linearly with circular overlap as impulse invariance ... Thus, using the inverse Laplace transform, the impulse response is math h c t begin cases sum ... s impulse response is then defined as the following math h n Th c nT , math math h n T sum k 1 N A ke s knT u n , math Performing a z transform on the discrete time impulse response produces the following ..., they can be mapped the same way, but the result is no longer an impulse invariance result the discrete time impulse response is not equal simply to samples of the continuous time impulse response ....
