Abstract

A method and apparatus for generating tone signals and the like in which a given frequency is employed for controlling a counter arrangement at a frequency which is equal to the frequency of the given signal multiplied by a factor other than a whole number. The multiplied frequency output when divided down will yield a frequency differing a desired amount from the given frequency.
