Sinc

In mathematics and engineering, the sinc function, denoted by sinc(x), has two slightly different definitions.

In mathematics, the historical unnormalized sinc function is defined by

In digital signal processing and information theory, the normalized sinc function is commonly defined by

It is qualified as normalized because its integral over all x is 1. All of the zeros of the normalized sinc function are integer values of x. The Fourier transform of the normalized sinc function is the rectangular function with no scaling. This function is fundamental in the concept of reconstructing the original continuous bandlimited signal from uniformly spaced samples of that signal.

The only difference between the two definitions is in the scaling of the independent variable (the x-axis) by a factor of π. In both cases, the value of the function at the removable singularity at zero is understood to be the limit value 1. The sinc function is analytic everywhere.

The term "sinc" (English pronunciation: /ˈsɪŋk/) is a contraction, first introduced by Phillip M. Woodward in 1953, of the function's full Latin name, the sinus cardinalis (cardinal sine).

The Power Of Suggestion

All Eyes on the system placed before you.
no time for an explanation.
Deceitful, why we dancing
if you listen
close enough
doesn't it feel, like a broken record.
Slicing through the skin
the sound has been over played and overrated
but the dance shop takes a long time dont it
we go round and round.
forget the heart, the life, the sting, the stage, the sound.
we go all round, this way
I quess the powers that we will see
it's time to make, our dicision and if you listen
close enough.
doesn't it feel, like a broken record.
Slicing through the skin
the sound has been over played and overrated
and do I excist to satisfy you
and satisfy nothing
Im right here and I hoping to be something,
to mean something to somebody at all.
but it's the same old song, one dance
with the same old song.
same old song, same old song, same old song, it's the same old song
same old song, same old song, same old song, it's the same old song
doesn't it feel like a broken record, a broken record.
I excist to satisfy you to satisfy nothing.
fear stares the wrong ways.
but right know Im hoping to be something
to mean someting to somebody at all.
