Abstract

The generator (1) has at least one sine wave generators (2,3,4) in the form of DC to AC converters. The oscillator (6) controls the generators with an amplitude signal set high or low depending on a phase value. The amplitude values are stored in an addressable memory. The oscillator's frequency may be set by a control. The frequency and amplitude may be set or queried through an interface (15).
