pole

Pole is the pseudonym for German electronic artist Stefan Betke. Pole is unique in that his music cirles around a broken Pole-Waldorf filter. The filter, originally designed to process sound information, now emits a crackle similar to vinyl hiss.

By taking this hiss and looping it, Pole creates a subtle backdrop to his forte: very ambient dub music.

Pole is distributed on Matador Records in the U.S., and was included on Mille Plateaux's Clicks and Cuts compilation.

Suppose a function f of the complex variable z. A pole of f is any value of z for which |f(z)| goes to infinity. If function f is only evaluated on the real axis, real poles of f cause it to reach infinity, whereas complex poles only cause bumpss in its absolute value. See also zero.

A complex function is said to have a pole at a point a if there is an isolated singularity at a and the Laurent series expansion around a contains only finitely many nonzero terms involving negative powers of (z-a). (When the expansion contains no such terms, we have a removable singularity rather than a pole.) If the Laurent series term with the most negative (i.e., minimum) exponent is (z-a)^-n we say that the function has a "pole of order n" at this point. Poles of order 1 are sometimes referred to as "simple" poles; for example, the function 1 / z has a simple pole at the origin.

Poles play an important role in the theory of contour integration, since the residue of a isolated singularity is easiest to calculate if the singularity is a pole, making the Cauchy residue theorem particularly easy to apply.

Pole, n. [L. polus, Gr. a pivot or hinge on which anything turns, an axis, a pole; akin to to move: cf. F. pole.]

1.

Either extremity of an axis of a sphere; especially, one of the extremities of the earth's axis; as, the north pole.

2. Spherics

A point upon the surface of a sphere equally distant from every part of the circumference of a great circle; or the point in which a diameter of the sphere perpendicular to the plane of such circle meets the surface. Such a point is called the pole of that circle; as, the pole of the horizon; the pole of the ecliptic; the pole of a given meridian.

3. Physics

One of the opposite or contrasted parts or directions in which a polar force is manifested; a point of maximum intensity of a force which has two such points, or which has polarity; as, the poles of a magnet; the north pole of a needle.

4.
