Dirac Delta Function
A generalized function that represents an impulse or instantaneous input, defined such that it is zero everywhere except at a single point where it is infinite, with the area under the curve equal to one.
Laplace Transform
A mathematical transformation that converts a time-domain function into a frequency-domain representation, making it simpler to analyze linear time-invariant systems.
Sifting Property
The property of the Dirac Delta Function that allows it to 'sample' a function at a specific point, meaning that the integral of a function multiplied by the delta function yields the value of the function at the location of the delta.
Impulse Response
The output of a system when subjected to an impulse input, used in system dynamics analysis to understand system characteristics.
