DDS Signal Generator Based on
The AVR Magnitude of Single-chip
Abstract:The frequency synthesizer is a very important signal source in some area such as the research, the correspondence system, the teaching experiment and various electronic devices. The direct digital frequency synthesize (DDS) is a new technology developing quickly in recent years. Advantage is taken from the inherent high resolution of the DDS, noise immunity of the loop, the short time of the frequency change etc. The signal source of DDS has many advantages including the small body, the low cost, the small power consume, the vivid control, and the high accuracy of output signal.
