An electromagnetic pulse (EMP) is an intense burst of electromagnetic (EM) energy caused by an abrupt, rapid acceleration of charged particles, usually electron s. An EMP can contain energy components over a large part of the EM spectrum , from very-low-frequency ( VLF ) radio to ultraviolet ( UV ) wavelength s. A lightning strike produces a localized EMP that gives rise to large electrical current s in nearby wires.
Digital signal processor. A digital signal processor chip found in a guitar effects unit. A digital signal processor (DSP) is a specialized microprocessor (or a SIP block), with its architecture optimized for the operational needs of digital signal processing. The goal of DSPs is usually to measure, filter and/or compress continuous real-world analog signals.
