Design of Digital Phase Shift Signal Generator Based on FPGA
Ming Pan · Microcomputer Information · 2009
According to the basic principles of Direct Digital Synthesizer, this article put forward Design and Implementation of the Direct Digital Synthesizer based on FPGA, and extend the output waveform of the frequency range with FPGA effectively. The signal generator used mainly technologies of direct digital synthesizer, a direct memory access, digital phase-shifting and digital AM. It improve and optimise the traditional analog phase-shifting arbitrary waveforms which can not be realized the shortcomings of the phase-shifting facilitate.
