Kronecker Delta - Digital Signal Processing

Digital Signal Processing

Similarly, in digital signal processing, the same concept is represented as a function on (the integers):

\delta = \begin{cases} 0, & n \ne 0 \\ 1, & n = 0.\end{cases}

The function is referred to as an impulse, or unit impulse. And when it stimulates a signal processing element, the output is called the impulse response of the element.

Famous quotes containing the word signal:

    “A signal is comprehended if it serves to make us notice the object or situation it bespeaks. A symbol is understood when we conceive the idea it presents.”
    —Susanne K. Langer (1895–1995)
