Design of Arbitrary Waveform Generator Based on Direct Digital Synthesis Technique Using Code Composer Studio Platform

Article Preview

Abstract:

This paper deals with the design of arbitrary waveform generator using the Direct Digital Synthesis (DDS) technique. The key idea is the utilization of Look-up Table (LUT) supported with Code Composer Studio (CCS) platform. The synthesized arbitrary waveform is generator by storing the samples of the signal described by mathematical equation in the form of LUT in the memory of TMS320VC5416 Digital Signal Processor (DSP) and subsequently by recalling the stored samples periodically. The D/A converter generated the analog waveform. Experimental results have been included.
