ABSTRACT:
A multi-phase signal generating apparatus is provided for readily generating multiple phase signals. The multi-phase signal generating apparatus comprises a signal data storage which stores a plurality of data segments for determining a predetermined period of one signal. A data segment selector circuit selects segments for constituting the phase signals from a plurality of data segments stored in the signal data storage for determining the predetermined period of a signal in each of a plurality of segment intervals which make up a phase signal cycle for generating a phase signal. Each phase signal generator circuit forms each phase signal using a plurality of selected segments for each phase signal during a plurality of segment intervals.
