ABSTRACT:
A method and apparatus for rotating cartesian coordinate signals x, y about an angle .theta..degree.. The apparatus converts the x, y signals into polar coordinate signals .sigma., .phi. and then changes the angle .phi. by .theta..degree..Theapparatus then converts the resulting signals back into cartesian coordinate signals x', y'.
